Classified (type) Script

I need a site where people can come and place ads with items that they want to sell so other visitors can contact them and then they make up the deal face to face, or some other way if that is what the agree of, but that´s totally up to them. This shouldn´t be an auction script and not a regular classified script. In this first module that i´want you to program there shouldn´t be any payment module included, so what you are bidding on is a basic version. You must be able to add a payment module later, plus adding more modules to the script if i want that. If you want more information, please send me a message where you introduce yourself and give me some links of sites that you have created. You will get a link sent to you that will give you more information if i like what i see. Sunpro
