create a site similar to pennyauction.com.my

I need a website similar to www.pennyauction.com.my. All the functions have to be similar or better, purchase bids, winner gets bid back, timed auction, small icons for the auctions etc. I also want to add a reserve function and a few extra functions to the website. Whats most important is the countdown and timer, it has to be perfectly smooth and no lag, bid butler has to interact well with each other. Eg, when two bid butlers are used, the first one bids first, and the next one bids the next minute. Not 2 at the same time. Even the page load must be quick and smooth, just like the site mentioned above. Everything should be in place, admin side should provide all the necessary controls for me to administer the site well. Whats most important is the support, I'd like to have support provided after the initial period in case I want to add anything. Make sure there are no bugs or anything in the site, all must be smooth and clean. I'll only accept if the price is right. If possible I'd like to see the website before paying for the website.
