But why do you want to do this for free? What will you gain out of the trade? Not criticizing you, just curious.
Good question.
I have never been an escrow before. Despite me being a long time member of this forum I feel like this is something that I can offer as a service.
Since I have never done this before I am always on the lookout to help newbies and inexperienced people so they stay protected and I start racking up "experience" as an escrow before I finally start to offer this service like other professional people on this forum and charge a fee for it.
