Game development for iPhone

Hello, we are looking for experienced developer, that can create the game for iPhone, We need to create the app fast (approximately in 2 weeks). Please inform us about the cost of development, beacuse the selection of the freelancer will be based on cost of application and experience of freelancer. About the game (it's very simple): There will be 3D scrolling of the camera forward. The point of the game is throwing knifes to hit the targets, that will appear on the screen while the camera moves forward. We're planning to create just 2 types of targets that will look like 2 different human. There'll be10 levels of the game. The decorations of the levels: the wood (trees by sides and grass on the ground), the castle (stone walls and floor), the garden (bushes by the sides), winter (just snow on the ground), etc... in general easy enough. We're looking forward to cooperate with you.
