Never transact anything unless the money is received via escrow, the buyer looks really suspicious i mean why would he need to contact an individual if there are tons of services online that offers the same task you're doing and out of all people why did he only chose you to contact, cause according to your story it seems to me that he's just a random stranger that contacted you.
He saw my
previous post. He's looking for a local product and to buy it with BTC. I don't see any problem as long as a reputable escrow is used.
