iphone application

I'm looking for a programmer that can program an application to run on iphones, the main idea is to process Fibonacci numbers and construct visual ramifications of the numbers in the iphone screen. I'd like to have the algorithm change with the user taps in real time, and therefore be able to make unique visual pieces each time. It would be great to be able to save the result as an image. I'll like also to have a splash with the name of my company and a configuration screen where the background can be chosen (a photo from the gallery or take one, or a solid color.) I'll expect comments and bids, details can be covered later. Thanks for your attention! Martin
