    This Freelance is very smart and capable. But beware! He is a blatant liar! Before explaining I have skype screenshots to prove (he will fabricate new stories like usual) He made the bot, but originally promised he would fix bugs and small issues-he said he would be available for upkeep, the moment he was payed HE WAS GONE! no replies for a few weeks, then he wakes up and says he will do, the gone again! He had the audacity to bid again on the same project, when I posted it again for someone to fix what He promised he would do. Punchline-He's not trustworthy at all!

    I believe that my design is simple, I need a bot to complete the form at the end of the link text.1 - The bot will need to get all the data into a txt or csv file what is best and fill in all the fields of the form.2 - There is also a simple captcha that needs to be combined with any recaptcha api to break it (leave it to the contractor to choose the API that best suits you and that you have good cost / benefit for me) might be able to bypass the captcha. always sending the same image and the same texts to let the programmer assess whether it is really possible.3 - After sending the data, store the return url in a txt and make a loop and move to the next data below.4 - The result is a return url with the server"s response to whether the transaction was accepted or rejected.The project is in monthly payment from customers, the time it takes to do it manually every month when you get the salaries you want is to automate putting the data and getting the authorization to give the same low in financial.Link form: http://gatewayirroba.com.br/wsredecard/wsredecard.asp?afiliacao=000094&total_price=11.50&payment_method=visa&payment_quantity=1&order_id=1457

    2 Things.1. Create a client portal in my wordpress site.2. Integrate an api into the client portal.The thought process: A company goes to my site and has the ability to run several reports for free using the api. The key for me is to get them to sign in so I can retain their email address and they can save/download the data from the api. On one page, I would like there to be a button that says "enter domain name" and the api will connect with the third party software and have the data flash on my web page (in a report format). They can then choose to login and save the report or download a pdf version of it.Hopefully this made sense.

    I"m searching for a developer who can write me a script that will export the details found on any NBA match details page, LIVE CENTRE tab on www.flashscore.com.For example: http://www.flashscore.com/match/8GjBuoQ9/#match-summaryI need all the details under the LIVE CENTRE tab (match summary, statistics, player statistics, lineups, match history) to be exported into an array so it can be used on my website.The script should update every X seconds with the new, updated details. Ideally the function will get the match code (you can see it in URL after /match/[match-code]/) as a parameter and the interval in seconds to update, and return an array with all the real time statistics mentioned above. The parsing should not take more than 5 seconds.

    I need a bot that will monitor & auto-purchase posters from the following site: mondotees [.com] Please visit the site and select one of the in-stock posters to see how the purchase system works—it"s quite simple.The way the site works:- The poster is released at random. The bot should be monitoring this and select the poster I specify (I only want certain ones, not all.) - It then needs to add the poster to the cart, continue to the payments page and auto-enter my credit card information / hit "Pay Now" to process the order.- OPTIONAL: If possible, I would sometimes like two different posters to be added to cart (rather than just one) before proceeding to payment. There are no captchas or safeguard preventing bots on this site. This needs to work very fast. Some posters are sold out within tens of seconds. The site sometimes gets overloaded with traffic and is non-responsive if you don"t purchase the poster very quickly. Thank you!

This would be a constant feed that would be going 24/7. I would need someone who is willing to help me set this up on a VPS or if they host the VPS, even better, we can work out an arrangement.I had this going in the past and can provide the Python code. It would need to be changed because I want it to do something different but might be easier to just recode from scratch.If you do a good job on this -- I will have many more jobs to send your way. People with experience using Tumblr API are preferred. In your bid, I request that you go into detail about your experience with feeds like this and show proof that you can handle this project. All "form" responses will be ignored. With that being said, if you have further questions, please let me know and I"d be happy to provide more information.

    We are looking for someone who has experience writing software for importing B2B sales orders into SAP Business One (B1). The software must be capable of taking data from a fixed format (which you may determine/dictate) and transfer the data (customer order/s) into B1 just as if the order/s had been entered manually. It is NOT a requirement that the software perform this functionality automatically, meaning to say that a person using the software will say "when" to import the orders. Since the functionality must be capable of handling B2B orders, an inherent part of the software interface must also be capable of extracting out of B1 files containing customer and inventory file data (so as to be certain that the correct customer is assigned to each order being imported, as well as assuring that inventory item numbers, and customer prices, are accurate in the order data coming from the form).IT CANNOT BE STRESSED ENOUGH THAT ONLY SOMEONE WHO HAS ALREADY WRITTEN SOFTWARE FOR IMPORTING ORDERS INTO B1 WILL BE CONSIDERED FOR THIS PROJECT. REFERENCES, TO OTHERS FOR WHICH YOU HAVE PERFORMED THIS WORK, WILL BE REQUIRED.

    I"m looking to have a tool that accepts an Amazon URL and scrapes certain data (which can be manipulated based on a set of rules eg. price markup etc) into a CSV file compatitable for use with eBay"s Turbo Lister software.Basically, I"m looking to scrape product listing information from Amazon, manipulate the scraped information, and export the list in ebay Turbo Lister format for easy importing.The system should then be able to post the created .csv file via Turbo Lister using various, randomly selected, professional looking eBay templates onto eBay. The templates should include the ability to show multiple pictures (if there are any) into the product description.This system would be able to put up many thousands of eBay listings very quickly, automatically once the URL have been supplied to scrape Amazon.Required Features:Input Amazon URL (accepts URLS after filters have been selected on Amazon"s site)Scrape product title, all available product images/urls, product description, bullet point description, product dimensions, UPC, price, inventory information, et.cCalculate and markup prices based on a customization markup table (ex Items 10-20$ -> 100%, Items 30-40$ -> 70% $80$...etc) Before posting to eBay the scraped information would need the price adjusting based on certain agreed formula and the Amazon titles would have the option to have pre-set keyword terms appended and/or prefixed to the scraped title. Being able to edit the title manually before listing on eBay as well as checking scraped content against a banned keyword list would be required too.Once the eBay listings are live, they need to be checked often automatically by the tool (would agree a time after asking your opinion on this) to ensure the scraped price hadn"t changed and the stock levels were correct. Changing the price/stock levels of the live listings as they change on Amazon would be required and the removing of any listings if the product gets removed from Amazon or stock levels reach zero.I would prefer someone who has done this kind of work before specifically with experience with eBay"s Turbo Lister program so they know what we are talking about.I appreciate this only gives you an idea of what I would like to achieve, and if you are interested I will list all of the finer points for you. In the mean time, please ask any questions you have and I while answer to the best of my ability.Is this something you would be interested in, and if so, can you give as much detail as to why you think you would be best for the job including any demos or links to similar work you have completed in the past please.Please let me know if there is anything I have missed you think I should include for or could be done "better", or if you just need anything clarifying before bidding.Thank you.
