473862 Penny Auction Script (Custom)

I am looking for some one to script a Custom Penny Auction web site for me. I DO NOT want a swoopo/telebid clone site. I am open to suggestions and am flexible with price in exchange for quality. Sites that have similar features as to what I am looking for are: [login to view URL], [login to view URL], [login to view URL], www.dealdash.com. I am also looking for someone that is willing to do continuous follow-up work to the site regarding maintenance, updates/upgrades, and new features. Please provide past projects and/or demo sites.
