Design for simple mobile game

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 "Apple Shooter" ([login to view URL]) and we need to be created some assets and animations. We need to create all design for the application: menu, buttons, toy/man toy, 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 )
