lowest unique bid auction swoopo, bidray, bidster

I have been looking for a good lowest unique bid website for months now, I am reposting this job due to time wasters. If you do not have a working website please stay away!!! I must see it working, so you must have the site loaded on a live server and I will ask for 3 user login so we can test the front end live and ensure everything works the way it should. I will also need an admin access to test the backend operations. The script must be able to handle up to 100 thousand users. I am not giving any detailed information here because if you have a swoopo clone you would know exactly what is included in the script. We will use a professional web designer to design our site and launch it, so all we need from you is the script. However if your design work is up to standard we can talk about it.
