Написать игру для app store

I'm looking to develop an action game for the app store that is geared towards teens. I know the type of game I want, and I already have some ideas on how it should look and play, but I need help deciding on the specific features that I want to include. I'm looking for someone experienced in game design and app development to come up with a unique concept and create the game. If you think you can help make my game idea a reality, I'd love to hear from you!
