Well except for the design and domain name there is not much around to be seen.Try to take it to the next level as it might have some potential and sell it then.Right now it's in the low xx range in my opinion.
At most I would say its worth a maximum of $10! but what do I know? Its worth what someone is willing to pay.
the idea is good, as well as the design, but difficult to say how much it worth,seems not many people visit this site.~
