Music Drills iPhone Port from C# Code

I have an existing C#/.Net application that I'd like to port over to the iPhone. I'd like someone who is familiar with music theory, is good at UI design and has created and published apps for the iPhone to port it over. The app is a series of music theory drills. The source I have has all of the music theory logic figured out, so there will be no new discovery there. Along with the source code, I have a fully functional PC desktop executable so that it shouldn’t be difficult to know exactly what I’m looking for. The program consists of: 1) Opening Screen 2) Drills Menu 3) Options Menu There are four types (sections)? of drills and a total of 13 screens of drills, though some of the 13 will use the same logic as others, so once you figure out the logic for one (or just copied the logic from my C# source), then you can duplicate it for another. Then there are three screens to change drill options. I'm only interested in bidders who have actually published an iPhone app? to iTunes and will require a NDA before I release the code.
