Clone of www.bizrate.com

Need to clone 80% of www.bizrate.com. Website must have search capability, to search based on price, location, popularity etc. Also to include designing & logo. Designing can be slightly different. Further 20% to be discussed, but shd be easily done as I already have something in mind. My own hosting ready. Bidder pls state timeline. If you bid for this project you MUST have a FULL understanding of how this site works. My budget is around 300-400
