SEO for dynamic e-commerce website

As you can see from [login to view URL] I've a huge product catalogue which is created dynamically from my suppliers CDI files. Now, ideally I'd like to optimize all of the pages but, I've an extremely limited budget so I'd suggest the following. The freelancer will agree to "SEO all of the Luminox Watch products". Consequently we're only talking about 80 pages so this shouldn't take too long. After this work has been done and when I see the results i.e, if sales have been generated; then we can talk further about the rest. Hopefully (like I expect) this work should pay for itself i.e. the profits will pay for future optimization. Best regards Graeme Nicholson
