Apart from an overall design makeover, we created a large number of custom fields for the products, and a template layout that made it easy for the customer to find the information needed to make a buying decision.
In addition, multiple galleries and PDF documents were required for each product and again, we simplified the process of adding these galleries and PDF files to each product. So we spent a great deal of time in the admin for the products, to ensure it was a simple matter of filling in the blanks for each product.
