Escrow System for paying another player to run the Trials

I hated the ascendancy trials. I don't find them enjoyable and more of a chore and will happily pay another player to run them for me. Actually they are the reason I don't roll a 2nd toon.

I think there is a huge market opportunity for people to charge for the aforementioned service, the problem is we need an escrow system in place so lets say the pre arranged price in exalteds or whatever can be held in escrow until the trials are complete, and then transfered.
