Hi, i can do it for you. I have vast experience in Photoshop, Illustator and Flash. You can view my portfolio at www.oxydesigns.com/portfolio
I terms of a quote, it really does depend on how well and advanced you want the banners to look, but I would say, for a good looking banner with abit of flash, about $5 a banner. Proabably even cheaper. We can talk about it.
