Yankee auction needed with a credit (point) system (no money used in this). User starts with a set number of credits (upon opening an account) and bids (at a specified time - 3 minute period) on a random number of the same item (units). There are three rounds. On close, highest bidders get first optons to buy up units but there should not be enough for all bidders, some must win nothing. In between each round the units are sold on behalf of the succesful bidders at a market price (based on a variable - number of bidders and total previous auction sale price), then the next bidding session/round begins (3 minute period). After 3 rounds the user get a summary page with graph on how they did and the auction ends with the winner having the highest number of credits. (more of a game really!). more details on request. The desgn will be done in house using a template/CSS you provide. We will also require a languge file for translation into other languages if required. You must be completely at home with PHP / MySQL and auction scripting. No money/credit card details will be used on this site so no security certificate etc. needed.
