Dear Op this type of trade i think it might not be possible as your account is new also no one is familiar with your trust history.
He is just a buyer, if he uses a Bitcoin or something similar to make the trade I don't think he'll face any trouble. Most of the time sellers are the ones who need more trade history to add more reliability. Personally, I don't mind trading with a newbie if I'm a seller, and I'm sure this is not exclusive to P2P trade on this forum. Of course, things can be different depending on how the deal was done, not to mention using a trusted escrow is also an option to secure the deal.
Which method would you be using for payment?
He seems to offer Bitcoin if you don't like Paypal[1]. He posted it on the wrong board though. OP, you should move that thread to Bitcoin marketplace, unless you also have other altcoins available to trade.
