I also have a dating site that has been up over a year. It is a FREE dating site business model with adsense currently, very simple design that could be cleaned up easily and made into more of an adult site. There are several thousand users on the site and it gets a small amount of steady traffic daily. This site could be fixed up and a few features added, or you could use the member database or whatever you need to do. The site has a PR of 2, no SE work has been done.
