Clone of Cargo-bid

I need a clone of cargo-bid.com. I need a clone of it in terms of functionality as well as in terms of layout. But functionality is more important for me. Its a reverse auction website. You may use any language and database. I just need my work to be done. I need it within 3 days at the most. And you should be available to be contacted via email on daily basis. You can use any available opensource script to get the work done. Feel free to discuss ideas in the pmb. My budget is not more than $80. Thanks.
