This sounds like you are evaluating the "Pro" version, correct?

1. I'm not sure about ratings for vendors as we don't use the Pro version, but each product can be rated by the customer.

2. The term "manufacturers" can be easily changed to whatever you like, it is a label variable. On our site we changed it to "Brands".

3. Banners can be added, but again I'm not sure what you mean by "individuals".

4. Depending on how you lay your site out, this should be fairly easy. It sounds like you plan to use "Manufacturers" as your various "vendors"... and there would be a "Manufacturers" list on every product page as well as a breadcrumb trail (i.e. yourdomain.com - category - product) on every page. Again, I'm not certain how Pro works.

I hope this helps.
