Make it easy.
Don't make the seller pay to get his docs notarized twice. Have a prepaid notary show up at his house instead after sending the seller a prepaid FedEx envelope to return the docs back to you.
Or better yet, pay the notary to send the docs back to you via FedEx. This way the seller does nothing, but sign the quit claim deed. Is it worth $100 to have someone else babysit this detail?
Otherwise, if he still won't cooperate, then he be not gettin' any money. Right?
