Excel built Pricing Calculator / Quote Generator

DUE TO THE HIGH NUMBER OF PROPOSALS I HAVE RECEIVED I HAVE CLOSED THIS JOB TO NEW OFFERS. Pricing Calculator / Quote generator. I need someone with strong Excel skills. The tool needs to be built in Excel. The tool is for a sales team to enable them to answer a series of qualification questions which will drive a pricing model to then deliver a printed quote out of the tool. The tool needs to have built-in flexibility to allow multiple product lines to be selected, line by line discounts applied, and also have a pricing table behind it to drive volume discounts. The tool also needs to have the flexibility to change the pricing model behind it, and add new product lines. There are currently about 10 products lines that his needs to accommodate.
