Character Design for iPhone game

Looking for a graphic artist to design 4 characters (3 will only need to be waist up as this will be a baking simulation game for iPhone.) I need a full character design similar to the female chef in this image: [login to view URL] a business man, old woman, and small kid in this style. ([login to view URL]) I am honestly looking to do this as cheap as possible, and as a graphic designer myself I understand the time frame of this task, but I just do not have the time to draw characters so bid low. For further compensation and to encourage low bidding I will gladly place your name in the credits linking to your freelancer page, facebook page etc to help drive traffic to you. Please submit a portfolio as well. Thank you.
