249321 Simple iphone app

I want someone with iphone experience to build me a very simple game application with a very nice interface. The game is very simple to build, as simple as sudoku and very similiar to sudoku. For example the game should have a very nice interface, with features such as 3 difficulty levels, records to keep up with your finish times. It should not take more than a week or two to make if you are familiar with iphone programming.
