Affiliate Banners required - repost

We need to create a selection of banners for 2 online casinos, inc. animated gifs. We have the main logo files, along with a huge amount of game graphics etc, that can be used. We can also provide what we need text-wise. What we need from the winning bidder is some imagination, and quality! We've had banners made in the past, which were grainy and low-quality. We would advise the winning bidder to look at the kind of thing that is out there already, and ensure we can catch the eye of the site visitors. The usual sizes are required - 468x60, 234x60, 120x60, 120x90, 125x125, 250x250, 120x600. Showing previous examples will help immensely! Also, we have a number of clients who are likely to be interested in producing banners of their own, so it will likely lead to more work.
