Are you familiar with Virtuemart for Joomla? I need a mod.

Hello, I would like to have an addition made to Virtuemart. [login to view URL] uses real-time bidding lists in each auction page. I'd like to have a similar list implemented that shows buyers and some of their personal info (First name, and Location ) in real-time. Each product in my Virtuemart store should have an independent list. Requirements: - A running list of the last 100 purchasers should be shown. Only 20 should be shown on screen at a time with the remaining 80 entries accessible by scrolling. - When a user makes a purchase, their entry(s) in the list must be highlighted if they're logged in. This is only valid if their purchase was one of the most recent 100. - The list must update as user payments are confirmed without refreshing the entire page. You can see an example of a [login to view URL] bidders list at this URL (The bidders list is on the right side of the screen) - [login to view URL] Please ask any and all questions.
