Classified project similar to many of the top sites

I really like the classified/listing service offered by super pages dot com and would like your bids to offer a complete solution very similar to that site with its clean and web 2.0 feel. Backend must be robust to deal with sponsored links versus listed ones and can differentiate between some elements that would make a listing fake. This project is not for North America. So keep that in mind. VERY IMPORTANT: COPY AND PASTE BIDS WILL BE IGNORED, PLEASE ADDRESS THIS ISSUE IN YOUR BID/PMB if you expect to win the project. Thanks.
