Html5 Mobile App: Multi-platform Multi-resolution Custom javascript

Front-end needed to connect to a web service featuring the following requirements: - Detect device resolution - Fixed horizontal position for smaller devices - Multiple CSS files for different device resolutions - Left side nav bar - uses Icons (no text) - three nav icons call a menu (may be JQuery mobile or other) - two nav icons call Undo and Redo functions - Use multiplatform framework such as Phonegap - initially, testing on iPad/iPhone only is acceptable - call camera API (may be through phonegap) - Most important: a custom color picker is required, this will involve HSB color scheme and three rotating rings (like a target, see documentation) and will need to be custom javascript. Please do not bid if you are not able to do custom javascript without using a library for the colorpicker. This also needs to connect to an online database to retrieve color information and store saved images. This project is for the initial work only, A follow-on project will be created once the prototype has been completed to connect to the completed web service and include some in-app e-commerce functionality. The finished result will be an app focused on interior design and allow users to virtually re-paint individual walls. Later follow-on work will include use of Facebook API. Please include skype information for serious consideration.
