Design a site

Hello Coders, I require a ready made clothe selling site, I want to make my business online, basic need is to show all of my products over the website there may be thousands of products so speed is concern for the website. I also need flash in it so it can have good look n feel. site I liked is http://www*wetseal*com/ (remove asterisks). I am unsure about the budget but open to fair price. I will also look into novice or new sellers over this site and who are masters, the only thing I need is detailed proposal from you which will show me all the details, what I will get, and which way. I will keep this bidding open for 7 days, after collecting all the proposal, me and my partner will shortlist everything and contact sellers who are shortlisted. Happy bidding...
