The customer experience will be essentially the same as shown on the example site and the parameters will be almost identical; just tailored slightly to our specific product line. 1 Customer surfs to appropriate page. 2 Customer selects parameters and submits completed form. 3 Zen cart displays results as in Product Listing page. Admin interface should NOT be built into existing product page, as explained above. Interface can be very simple. I will even consider an interface that simply downloads and uploads a CSV. Also, as noted above, this should be a separate table from products to keep from messing with several other modifications under way. So, essentially you have just a form on the customer side and a form on the admin side feeding and pulling from a single table.
