The vast majority of transactions go smoothly and have no disputes, and as a result the most difficult part of the transaction is writing up the escrow agreement, however most trades are standard enough so that templates can be used for the majority of escrow agreements.
Running escrow is far from a full time job, although the per hour payment for the work involved in acting as escrow is going to be far above of someone flipping burgers at a fast food restaurant, even at somewhere where the liberals have made the minimum wage $15 per hour.
id like to ask, around how many escrow requests do you get in a month on average given your reputation on the forum?
