Penny Auction Site like swoopo

Hello, I need someone to create a penny auction website, i am looking for something along the lines of swoopo or bpowerhouse.

If you have any better script, i would love to see what they cost to install and get everything set up.

SO all in all, i need a penny auction site that runs efficiently and without any crap like bots or anything.

Bid Away!!
