Design for simple mobile game (WP7 and WIN8)

We need a designer of a game for mobile devices (Windows Phone 7 and Windows 8). The game is simple and will be given all information to start design the game. All we can say is that the game is based on "Run Doggy Run" ([login to view URL]) and we need to be created UI assets and animations. We need to create all design for the application: menu, buttons, turkey running, man hunter, obstacles, animations/sprites. Requirements: 1. We need to check Portfolio (or make us a test design) 2. Fast working (max 2 weeks) Winning bid will be between 30$-120$ ( it is not a high-budget project )
