Game development for IOS and Android

I need a game for IOS and Android: Rough Details: Left to Right run level-based game, like *Mario* Move Left to Right, killing bad guys, collection coins, etc etc. Left to right concept. With Good graphics. I need someone who can design pretty, sleek looking graphics as well as the code for the game. I have a story line to the game, and much more to it than that, but that is the basic idea. I will discuss it in Private.
