Multi Store functionality in osCommerce

I am looking for someone to add multi-store functionality to a fresh install of osCommerce. - Each store must be configurable and controlled from one admin panel and database. - These will be affiliate stores and will be setup as sub-directories to the main domain. As such, there would be minor changes to storefront themes, but categories and pricing would be the same for each store. All categories, products and pricing are controlled by the main admin panel and updated across the board. - The admins back end must keep reporting separate for each store, so that commission structure can be calculated and paid out. - Each affiliate will have access to certain parts of the back end, to view sales reports, for their own individual storefront. - Is there a way for this to be setup, where the main store is not an active store. No products sold from the "core". Only the affiliate stores would be live, selling product. - availability of separate shopping carts, with personalized checkout. I have seen a multi store contribution on the osCommerce site. It seems to be able to do what I need, however, I am unsure how to install and configure the code and databases to make it work. Thank you.
