Simple iPhone Game Development

I need a simple iPhone game developed and this should be easy for anyone who has developed iPhone games before. Graphics for the game are minimal but the splash/option screens need to have good graphics (for game branding). The game will make use of the iPhone's accelerometer. Since this is a simple project, I'm only looking for development costs which are under $1000 and which can be completed as fast as possible. The lowest bid and quickest time wins the bid. I actually have 2 games in mind. If you complete one, I could give you the other too as another project. You will need to show me iPhone apps/games you have done in the past with your best graphics. You will also need to sign an NDA. If you are able to do a project quickly and with the lowest cost, reply to me and I will give you some details. You will be paid upon project completion. For complete details, respond here. Amin
