Create a Native Android and iPhone App -- 2

A fairly dynamic and intensive android and iphone app in the fantasy sports realm. features would include dynamically making rss/feed calls, charting, and fair amounts of working with sport statistics...and in-app payments to unlock different features within the app. I work in technology, but don't have much time. I can layout design and activity flows...and will be working with statistics and database on a webserver which the app would hit to retrieve data for statistics display, and charting. I know this will not be an easy project, and would take time...
