Simple ipad sliding puzzle game

Hi, We have a simple iPad sliding puzzle app, which we want to modify slightly and apply new graphics. I will provide you with all the designs and need the app to: - open up with a landing page first - apply all the graphics - display the selected puzzle on entire display with retina display resolution (it displays the image on 2/3 of the display now) - each puzzle should end with its own sound file (will provide the files) - in-app purchase for unblocking the full version (making it into free version and a paid one also is an option, but would prefer in-app purchase solution). This is a small job and we would prefer to work with people who already have some experience in puzzle game apps. Looking forward to you offers! THX
