you do not want to be scammed use an Official Middle Man for all trades.
I will MM any type of trade with PayPal, and my fee is a flat $3 per trade. You may feel the fee is a bit high, however it is a small price to be paid to be guaranteed you won't be scammed.
That means I MM: Accounts for paypal, Pins for Paypal, etc the only thing I don't MM is gp.
