Create Joomla Based Site.....expert only

I need a mall feature to work within a shop mod. The main functions will allow users to sell items in their own store using the alpha points mod as the currency. I have a spec sheet that explains exactly how things will work. The spec sheet is really old and states functions that I do not need. so when you see it don't let it overwhelm you. Basic Functions Users list items they have for sale from items in the db Other users buy them using the points mod Item descriptions box art and other info must pull from Amazon API Which I believe there is a mod for. The ability to leave ebay style feedback for the seller. Not needed for the buyer since he is paying with points. The items are all video game and movie based. --------------------------------------------------------------------------------------------- budget:-250$ time:-10days must start now and give me update in 2 days
