So wait you sent him $2500 and he's a newbie? Dude you're fucked 99% sure. Congrats you got scammed. Can easily cash that out via online credit card as we speak. USE ESCROW. easy way of scammers to make themselves sound like a hero to earn your trust.
Either you get scammed or you're a fake account of the OP.
Using Escrow for paypal means that you are dragging someone else to danger. I suggest not to do any PP trade unless he is trusted.
