    Small bit of work on data retrieval

  • $500 USD In Progress

    We need a price comparison site designing and building. The wesbite will compare ticket prices from 3 major websites.The website will need to collect data in real-time and not stored aggregated data.It will compare ticket prices collected from data from 3 websites. The customer will have the abiliity to click on the ticket to purchase, which will then direct them to the correct website... at the correct page, so all they need to do is check details and pay (our website will not be taking payments at all so please do not price for that). It must not take them to the homepage and have them go through the whole process again, IT MUST TAKE THEM TO THE CORRECT PAGE OF THE CORRECT WEBSITE, FOR THE COORECT TICKET.It will need the ability to track purchases so we have an exact record of how many people we have succesfully tranfered to purchase and the amount who have actually purchased.Google - Once active, the website must list top on google for its sector and sub-sectors.Payment as follows:50% will be paid once the website is online and functioning correctly.25% will be paid once listed at top of google as per above.25% after 3 months correct operationOr if you would just like to bid for the scraping part the following payment plan is in-place:50% when published and after 1 -2 weeks testing50% after 4 weeks of correct funtioning.PLEASE NOTE THE INTERIM PAYMENT SCHEDULE ABOVE IS VERY MUCH ONLY PART OF THE BIGGER PICTURE AS WE SEE THIS AS AN ONGOING PROJECT, WHICH WILL BE FAVOURED TOWARDS THE ORIGINAL SCRAPE DESIGNER.We will need to own the rights to the source code.Any Questions Please ask,Many Thanks, SGI

    We are looking for a historical database of all applications ever to appear on android market including price and ranking histories.

  • $1500 USD In Progress

    I need a php script that reads URLs (e.g. www.ibm.de) from a MySQL Database and alternatively via a simple php function call that receives a single URL as well as the country code of the website-operator and then 1.) fetches the website2.) searches for the occurance of a link (a href and onclick=location.href) to the contact page / imprint / about us page (list of words/strings to search for should be defined in an array in the config file for the script including priority what means if a word with higher priority will be found, the Script will search on this page first, if the Script finds contact data there it stops searching for that domain). Priority can be done by order of array values. 3.) Extract contact data from the site and save it in the suitable database fields like Company Name, Street, postcode, city, phone, Fax, Mail, CEO, tax id, company registration id in case the URL was read from DB or return tha data as Array in case the URL came from a function call. To make extraction easier I provide a Country Code for each url. Based on this code there have to be rules how e.g. adresses might be formated (Syntax). In this project only German (AT, DE, CH-country codes), UK and US adresses have to be extracted. Each country code should have a OEM configuration file, so that the script could be adopted and extended in the future. If no Country Code is given or there is no cnfiguration for the given Country Code, the Script should Report an Error. If data could not be extracted, it should save the URL to a table for further optimization of the script trough configuration or future development. The script should extract at least 85% of the data in a random selection of 500 URLs for each of the 5 country codes. Script should be documented very well and I need a written explantation for the configuration files.Finaly I need a second script to compare the perfoemance of two different configuration files for the script above. This script should take URLs and Country Codes from an own MySQL table and run the extraction for both configuration files. It should write the extracted data to two different tabels and compare how many data objects could be extracted (e.g. counting phone numbers in table a and b and so on) and should show database rows with different values in a table view highlighting the differences. This script is just to optimize configuration files and needs just basic GUI Design.

    HelloI have a website which is under Construction .Unfortunately The programmer I hired Cannot finish it due toTechnical Problems which he doesn`t have the skills to cope with .I`m looking for a skilled programmer which : 1. will understand perfectly the site code. 2. will be able to cope with those problems .The Problems are : 1. Slowness - the site performance are not good , It takes long time to load , the site code should be imporved .2. I have an application in the site that copys links of movies from other sites and puts them in my site .The problem is that it doesn`t put them under categories - Comedy,drama....etc3.The site users will be able to comment (talkback) on the movies .4. There is a problem in internet explorer browser that when you press on a movie it doesn`t appear in the TV borders - If you play the movie on Firefox browser it runs ok.The site should be checked on all browsers.5.In each online movie link the user will be able to see the movie trailer below from youtube site.6. In each online movie the user will be to watch it with no time limit using the site http://www.megavideounlimit.com/megavideoThe movie will be played using this site on my TV .7. The option of Mouse Double click on the website will be disabled - I want an option to control it ( if i will want in the future to able it again ).8. I want the application (that I described in paragraph 2,the one which copys links) to copy links from the website http://www.wnet.co.il with all the categorys on this site .The links will be shown in the exact display as the display you can see in my site (and not as in http://www.wnet.co.il site) .9.I want to disable to popup advertisement that jumps each time the user press on movie link.10. I want a chat program with rooms for each subject like sports , hebrew\english users etc...11 . I want that in the front page of my site the users will be able to see the movie categories and one picture (that wil change automatically) from a new movie link that was added recently.12 . - very importent !I want a button that will expand the screen movie – instead of letting the user expand it .It can be made because when you see a movie in mega video the full screen button is always on the same spot in the screen .13 - very importent !I want that when a user press on a movie,the movie startsautomatically (the user doesn`t have to press the play button twice on megavideo screen - the site does it for him)14 . In my site there is a joomla module of justin.tv which is used to broudcust movieson the tv on site from the website http://www.justin.tv/ ,I want to add another joomla module to the site - live stream module which will be used to broudcust movieson the tv on site from the website http://www.livestream.com/ (there is an embedded code in this site that can be used to do so). 15 . Better web site design.
