create seo friendly product database for oscommerce website

I have a demo os commerce store set up temporarily [login to view URL] I have images, pricelists, descriptions, sizes, from the manufacturer that I need to be converted into a database for the store. the product and category pages should be seo friendly urls, titles, descriptions, keywords My website was also hacked and a malicious script got on there Im pretty sure I removed the script on all of the pages but it looks like it messed some things up. So I basically need someone to create and implement the product database and help me get it to where people are able to place orders. I also dont want it to require them to create an account on checkout that should be optional.
