Hi, I'm a student studying Computer Science, and I have been working with Unity 3d for game development for iPhone in a company for the past 3 months. I will be able to make your game, as you want if you already have the graphics of it. I'm new in freelancing and I don't have yet a portofolio put together but if you send me all the materials, I will do the game and if satisfied you will pay me. :)
Cheers!
