Change design of a pre-maid game

Hi i want someone to change the design of this game, in fact, i want 2 designs. One would be an boy just like this but with different clothes and different background. The second design would be a background of an lake or something like that and a frog would be running instead of a guy. I want the art to be cartoon like the game. I have all te game source codes, the design would receive the FLA file and then send me back the final FLA with all the arts already working on the game, because my skill with flash is not advanced and i would not know how to transport from photoshop or ilustrator to flash. The game url is : [login to view URL] I dont have hurry, so if you charge less for more time to work then that would be fine too, depending on the amount charged the person would need to split the value in two or three times. Thanks
