I am contemplating selling
http://www.WebRealtor.org - the domain name is registered with godaddy for aprox. 11 more months now (has been registered and owned by me for the last 13+ months) and the software that runs the site is freeware, a backup of the database is included.
Traffic for the site is generated from a few link spaces I bought which expire shortly, and from having the link in my sig on numerous sites.
Stats for July were 445 unique w/ 2700+ page views
Stats for August were 457 unique w/ 2300+ page views
Stats thus for for September are 137 unique w/ 5900+ page views
The site is 100% free for people to use, and catagories and subcatagories can be added and removed very easily.
The site has made some money each month via adsense, but I feel it could easily make more selling adspace outright and / or utilizing some related affiliate programs.
I am currently accepting offers of $100 or higher, payable via paypal
