If your traffic doesn't convert, your "potential" dont mean shit....
You should really think about what it is you're selling..
Just to give you a fucking clue

Most good sites sell for a lump sum of what they generate, lets say your site earns $1000
per month on an ongoing basis, you could expect to receive anywhere from 3 - 6 months
revenue. So from $3000 - $6000 depending on how serious the buyer is, some time ago
sites were selling for 1 years revenue.
But anyways if your site dont make shit it aint worth shit........
Good luck in the big bad word.
