If you guys want, you can use me as an escrow as I know the account and even have the signed message from the OP... 
Beware, people with no trust that offer themselves to be escrow may receive negative trust
How can they get positive trust if people would -ve trust them if they try to offer a service that requires +ve trust? I'm not saying that you'd go escrow with him but I think that's just unfair.
people can get +ve trust if they offer services or do trades first and not offer escrow service first to gain trust.
I always wanted to do escrow for such deals, I know that I never did such deals before, but that doesn't mean you can't trust...
There's always a first-time for everyone, which is why I thought to ask to become an escrow in this case...
Anyways, the decision remains with the OP and the buyer themselves, I ain't forcing anyone to use me, I just made a request...
And about trust, who says I have 0 positive trust???
Please do check my ratings, I have repaid a 3 BTC loan after just 1 day with 10% interest, I ain't vouching for myself saying that, but that's not an easy thing...
If you don't want it I will take it for your last bid or my invalid bid though.
