Oscommerce modules

I have a oscommerce store. I want be able to show the users on some products Retail prices and discount prices. When I set a discount price for a product, then the retail price need to be crossed out, and show the Discount price in red. I have seen this in lot of sites, and know, this is just a small task. Lowest bid will be prefered. Please bid not more than $10. Must start immediately. Thank you
