If you want to sell it, create an auction on http://www.flippa.com
If you're asking more than $1000 for the site, only accept payment through escrow.com.
Flippa's the best marketplace there is for selling websites in the $50 to $250,000 range. I've sold several sites there in the past, including one for $90,000 which had several serious bidders. There are real buyers there.
