I will design the Characters (Very Cute by the way. I can mimic the style exactly if you are using some characters like that already, or I can develop the similar style). I priced for four characters and the logo. All at $15 each. So that is my price. I would like to work on this. Contact me.
(I work mostly with Photoshop for drawing and images, and Flash for the vector drawings. Which is what these characters will be - that way you can scale them up or down depending on how you want to use the characters. And as many places as you like).
