Vendor Quotes/Pricing Changes

We handle a decent volume of pricing quotes from our vendors. We’re looking to set-up a website where we can login, define the product requirements for our manufacturers and assign certain vendors to be able to quote/bid on the item. Then our vendors can login and submit their quotes - confidentially. Perferably tied straight into Navision. I know this sounds similar to the “reverse auction” functionality, but I’m not sure an auction format fits our business. Additionally, since I’m deaming now, it would be nice if the site could also handle submissions of price changes from our vendors and we could accept or reject them…again updating Navision if we accept. Thanks in advance.
