Build a Cross-Platform Mobile App

Hi, We are looking at building a cross-platform mobile app, based on our website; using either one of the - Appcelerator Titanium, PhoneGap, Sencha Touch or JQuery Mobile frameworks. Developers are requested to provide a custom proposal stating which framework|platform they will build on, the features in the app they can include (think about everything possible, here), the time they will take to complete the project and their budget. Please don't spam bid, BIDS WITHOUT CUSTOM PROPOSALS WILL BE REJECTED. Thanks, for your time.
