osCommerce Category buttons

Hi, I need someone to create category images to blend in with my site at [login to view URL] I like pictures like [login to view URL] but with obviously all my categories But I also like what this site [login to view URL] has done at the very bottom of the page, the rollovers, prefer these but obviously would have to be totally new designs as not to be reported for copyright breach. The best designer / bidder will get on going work as long as the price is right.
