OP, with many other escrow agents available, and with many of them having lower fees, and more reputation, why does your service exist?
I am aware that green trust accounts can be bought and sold, but then, I've seen low ranked accounts traded far more often.
Based on your trust, it looks like the most anyone has ever risked in a trade with you is .01 BTC.
Now I'm no whale, but for escrowed purchases, that number seems a tad on the small side...
Instead of trying to be an escrow at this point in time, it would likely be better for you to trade more in the marketplace, and build up a solid history of good feedback...
