Create iPhone and Android App based on existing Mobile website

I have an existing ASP.Net MVC 4 Mobile website at [login to view URL] that uses JQueryMobile and connects to a ASP.Net Web API (JSON or XML) RESTful API. I do not have great ObjC or Java skills- but I need an App for both platforms that replicates the functionality shown on that Mobile website. The API is documented at [login to view URL] so you can understand the API you would be connecting to. The only additional functionality not currently shown in the Mobile Website is an In-App purchase process that gives a user access to Attend an Event. Currently the Mobile Website allows users to access for free. The design and UI of the Mobile website is guidance only. It is preferable that you use appropriate constructs and conventions in Apps of each platform to improve the user experience rather than simply replicate it screen for screen. As such, a portfolio of previous work is required, and the slickness of the design of previous project will be an important criteria in selection. it is preferable that each App is natively developed rather than using PhoneGap, Titanium or another cross-platform web framework. Having said that, if your portfolio shows you can use HTML5 + CSS to produce good quality phone apps, and that is your approach preference- that will be considered as an option. Each use case (or small sets of use cases) will need to be reviewed as complete throughout the project- as opposed to waiting until the very end of the project before I can see progress. Please consider that when making your bid- as this has been made clear at the outset. A source code repository will need to be used: either TFS or SVN. Preferably the former, but if SVN is a strong preference- then that is fine too. Please have a look at the Mobile website BEFORE making your bid, as the functionality of the website indicates the scope of the project. Some screenshots are attached for reference.
