Simple 2D Jump Game for iPhone

I have a quote from another provider for $1200. If you have better skills and can do this for less than $1200 please bid. Otherwise I don't want to waste your time. Thanks. The game is a very simple jump game in 2D but the graphics should be of very high quality. I don't have any graphics so the service provider must do the the graphics as well. I assume most of the work will go into graphic design as the accelerometer controlled game should be easy to do. OpenGL or UIViews is your choice. If this project is a success an iPad project will follow. Please see the attached file for the full description of the game.
