This doesn't prove anything, but still being an escrow requires more time and more trust, more trades between users.

I'm not saying you to leave but it;s just too early to offer such a service for the community, take a look at this thread https://bitcointalk.org/index.php?topic=855778.0 and check who are the users that offer escrow service, their thread, their reputation and how old they are in forum.

Thank you...
