Originally registered for a business venture, but opted to go a different direction. Currently parked at TrafficZ with i-0.com receiving about 1200 landings to date this month.

Would like to sell as a group. Any suggestions as to valuation or where to market?

TIA

I came across some like this while looking for some domains on godaddy, though they were worthless. Just recently I saw one very similar to those selling for 500$US. If it gets 1200 landings in less than a month oviously I have no clue about domain values.
