iPhone/iPad Game App Development - Game Design

We need a game developer that can develop a game app for the iPhone and iPad. We are looking for someone who has apps in the app store and can provide demos of their work. You must have good graphic design skills. Excellent written and verbal communication skills in English is a must. If you have the needed skill sets and can provide quality results then I will have future projects for you. We need a game that we can upload to the app store, publishing it under our company's name, and inside the game we have to be in the credits as developers of the game. The game design and graphics presented must not bring us any problem with copyrighted material and/or games published by other companies. I will provide a detail description and ideas for game development to selected provider.
