Design for ipad/android puzzle game for kids/children

Hi, I am looking to make a puzzle app for kids. This part of the job will only consist of the design. The programming I would like to have done by a seperate company that is specialized in programming. There are some games in the Ipad that are very beautiful, and I would like the puzzle to have some of those aspects. This is the style I am looking for: [login to view URL] and [login to view URL] It's very graphical, but this is how it should be. There will be a story board made, and the screen will scroll like the puzzle in: [login to view URL] The design should be organic, fresh, but also understandable for kids from 1 to 4 years. Greetings, Guy
