I need 3 website banners in 3 different sizes; 160x600, 300x250, and 728x90. The banners should be in .gif or .swf format. The banners should also have a small amount of animation. I want the banners to be simple, yet effective. The goal of these banners is to get the highest click through rate possible. As soon as the winning provider is chosen, I will give the exact website that these banners should promote. It is a sports related website. The winning provider should be able to take the concept of the website and product that it's promoting and be able to come up with a creative solution. Payment will be made using escrow.
