Looking for unity programmer

Hello, I have a racing game that I need animation for. The game was made with unity. I am looking for someone with experience with unity. Your job will be to add function to the characters in the game with a simple animation, setup the payment tiers, add one menu and submit the game to the app store. First, I need for you to do is to program in the payment structure into the game. The game already is approved for iTunes payments. The payment will unlock the cars that are currently locked. Next I need you to animate the individuals walking -they should fly over the car and when the car loses all of its health it should explode. Last, is to add a menu submit the game to the iTunes store. For bidding and payment: I will pay you a milestone when you submit the work back to me to check and the rest when the job is complete. Attached file contains the url to the itunes game.
