penny auction script needed

I need a 100% working Swoopo/MadBid Quibids script or Penny Auction Script. 
1. Bid Butler and automatic bids should definitely work . 
2. Demo definitely required for even considering the bid.
 If you already worked on this project provide many urls demo. I might ask you to customize a page to proof that you own the script hosted on the domain you provide. 3. Script should be able to hundle hundreds and thousands of users online. [login to view URL] should be open source and 100% customisable. 5. Lowest bid amount for the script will win, the better the script you have the best chance you have to get the project. You will have to install the script and make it work on my domain before I release the milestone. Failure to install a working version on time as you provided in demo will result in milestone not released. You will have to provide an invoice through freelancer If the script is good enough i will probably outsource from you customisation.
