Hi,
I saw your ad, it sounds like a cool concept. I'm a fairly versatile illustrator, you can see some of my work here>> http://eric-c.com. If I'm selected, I'll provide 3 rough sketches and you pick the direction you like. I'll then finalize that and get you the finished version within a day, taking into consideration any feedback you may have. I look forward to hearing from you.
Best,
Eric C.
