Design Graphic Icons for Videogame Accessory Site

We have a retail store that sells videogame accessories. The site is 99% designed. We have a number of subcategories for which we need a 174(w) x 120(h) pixels icons designed, fitting in with the style of the site. The text for the icons is already taken care of, so the icons just need to be a graphic representation of the category represent. In general, the icons will just need to be an image of eg an ipod, PS2 cable, Wii controller etc on a background we can supply. Please bid and show your previous work and estimated time to complete. Contact me for further instructions/to view the site in question. There are approximately 400 icons required, but approx 20% will be able to be recycled.
