Touch/pressure sensitive iPhone game

We would like to create an iPhone game with 2 versions. A lite version which will have a limited set of functionality from the full version of the game. The game has a simple background that goes form day to night and has objects on the screen. The user should be able to interact with the objects in the screen by swiping over them. The game should recognize the pressure of the touch on the object and will behave differently depending on the pressure of the touch. There will be 4 types of objects on the screen with very similar feature but with a difference on touch sensitivity/pressure. We would also like to have a scoring system for the game to keep a local leader board, global leader board and a Facebook friends leader board. Finally we would like a simple instrumental music in the background to play continuously. NOTE: your bid should include costs for graphics and designs. Also please include sample of your work with your bid via PM. thank you!
