I want a classified ad website. I would like for it to be search engine optimized so that every ad posted will be searchabble through google. I want to be able to sell banner ads at the top and bottom of each page and sell add links on the side of the page. I would like google adsense intergrated into the site. There should be a free and paid package and lots of upgrades that cost so that I can get revenue. I want new users to have a verified email.
