"Earns $5290 per month from pay-per-click advertising (30-day-average)"

Thats about 60k a year, thats enough to live a regular life without doing anything but owning the domain. A full-fledged web site with a community some paid services and good affiliate programs, you're looking at 7-10k a month minimum - again doing nothing.

This will sell for at least 200k, easy.
