Classified Ads Website

I am looking for a Classifieds/Ads Website to be delivered to me. The site should be similar to [login to view URL] and [login to view URL] ? and [login to view URL] in terms of functionality. I am outlining the essential functionality of the site here. 1. Users should be able to post and view ads. 2. They can post Ads in different categories 3. Localization will be implemented so that whenever a user visits a site, he would be presented with a list of countries then state/province and then city to choose the ads he wish to view. 4. Admin Panel - Should be able to do anything and everything on the site. Examples: Edit ads, block ips, delete ads, place ads on site, view statistics ..etc. 5. All ads related data will be placed in MYSQL Database. NO CMS? I want a classifieds website with the web 2.0 look and feel. I need to have all the major categories on a classified site, this is not a specific market related site, people can put anything for sale. This can be based on a script being sold and customized in the internet or can be a built from scratch project. I want a free and paid site, however users must have a private area to manage their adds, i want a favorites sections where users ( registered or not ) can add some classifieds to a favorite list, and i also want users to have the ability to pay to have their adds in the front page or in relevant positions in the listings ( direct listings or search listings, banners ). Users must have the ability to add photos or videos. Remeber: the look and feel of a web 2.0 site is very important. I want a simple site, but it must look very professional.
