    I want a simple OSX app written in RubyMotion(I would prefer this in RubyMotion but may accept ObjC candidate.). I will give you a URL with JSON which needs to be monitored for changes. The App will be a simple app which puts an icon in the system menu and will notify on changes. An authentication will need to be entered in a preferences screen so that the user will be able to connect to the server and get the details.A simple iPhone app should also be developed which is just a dashboard showing the same information.

    Hi, we&quot;re a UK startup developing a webapp around street art and graffiti. The site is hosted on Heroku. A key part of the site we&quot;re looking to develop is aggregating and ingesting content from other sites around the web. I&quot;m a developer myself but would like to speed up this part of the site by getting outside help. I&quot;m looking for help developing a prototype version of a cloud worker (IronWorker?) that can scrape sites according to rules and process that into the main web app. An example of this would be a lifesteam section to artist profiles where facebook page updates / photos posted to flickr would be shown as a aggregated feed.Have you had any experience with developing cloud background workers using rails before?Many thanks,Daniel

    Hello I read good reviews about you and want to ask you to read my request.In few words I want site looks like http://www.nationalgeographic.com/I mean menu and structure in general. Some detail are bellow.If you can do it I want to know the price for 2 part (1st just site with no payment optional 2nd with order form)Website for online travel agency.1. Easy to use admin panel for person who knows nothing about php, mysql etc.Easy add photo, text, links, ect2. MUST BE OPTIMIZED VERY WELL BOTH IN CODE AND EASY TO USE PART.All materials i.e. pages must be stored in mysql database. I have host that supports it as well as another main options.And give the access to it.3. Cross browsers compliant. CSS has to be well coded and documented. Light and W3C compliant in HTML5.4. Totally 9-10 patterns (1024px wide), PSD FILE are allready DONE.5. No wordpress please. Maybe joomla 2.5 but ready to listen your advice.6. Main menu has up to 8 buttons, submain up to 8 for each main.7. All pages will contain the same header and footer.8. Facebook, Twitter and subscribe button must be integrated.9. Some page will contain photo slides, pictures 450x300px or less (ATTENTION: I want you to do it by Ajax or something like that NO FLUSH)10. The content of almost all pages will look like http://www.travelzoo.com/?site=us or site like that.BUT will have bigger pictures and part of some of pages will need space (frame) to integrate later affiliate form of booking.com and another fly, car etc company. More details will be send to candidate who preliminary will be chosen.11. Two easy forms like: name, surname, email, query with mandatory field before sending. One for customer, second for company.So nothing extraordinary.Behind above mention I need next ORDER FORM (it might be integrated with any e-commerce solution for example opencart ):Some kind of order form when people chose different option like: date in, date out, city from start, cities for visit, air ticket, number of people, age, email, name, field for wishes and some moreAfter press order (or buy) button the system MUST check errors for incorrect date in and date out or failed mandatory filed like terms and proceed to payment page. When customer changes option (i.e number of people or cities) the system must show him the current price. If form complete in right way after customer press &amp;acirc;€œorder&amp;acirc;€ button this form changes to last form (payment page) when person can read what he/she chose and chose payment option for buying.Once person buy the email notification with attached the same form that was at payment page must be sent to email that was typed and copy to our email and order put in database.The realization of this form might be in way you think best suit for reliability and friendly to use.The date in and out should be like typical calendar. The city from and city to in ideal should be realized like here http://www.momondo.com/ Please let me know if this part (chose cities) very expensive (give me the price of this), Maybe we can do it more easy. Customer will manually type in these filed. Rest of fields easy to intergrade so nothing special requested.ORDER FORM ABOVE IS FULL ONE. Also I want to have ability to remove some fields from it to provide another form for another type of service totally based on this form i.e. no additional fields required!For example start day or period of date and/or cities will preselected by me. Further process of ordering the same as described above. Realization might be discussed as well as any another part of project.OPTIONAL (especially video):1. Possibility to add audio only for listening no payment option required, simply embedded for customer use. Idea something like this http://promodj.com/ but not copy! Only idea.It is my first project and bound with money but I want to make good site with your help, that is why I ask price for separate parts that I am going embed in my web.THANKS
