I am looking for B2B script that is a hybrid of alibaba, [login to view URL] and [login to view URL] Global and alibaba are suited to promote large manufacturers to wholesalers, which I want to include, but mainly as a wholesaler to retailer ability with catalouge and/internal site as with gpoint which will be the main site purpose. I currently have 4 DB sites running in php-nuke so it's what I know.
