It usually works that buyer sends BTC to escrow like minerjones, then seller sends coin to minerjones ( not you). As soon as he receives coin from seller he forwards on the bitcoin ( minus 1%), and then forwards on the coin.
No problem, this method is acceptable too.
EDIT: also note insurance is impossible on bitcoins, I use the above method to import into Australia frequently, but if it gets lost/ stolen in the mail after escrow forwards you the coin, you are shit out of luck, and will lose your bitcoin.
