If he's happy to pay for shipping then surely he's happy for for you to deliver by hand, probably cost less in fuel than shipping costs.
I bought a Variax recently on Ebay, it turned up with one thin layer of bubble wrap over it and a single, flat layer of cardboard taped to either side of it, the cardboard didn't even meet up at the top or bottom
.
This was sent from a shop and the listing stated "This will be packed carefully and will be shipped in a new guitar shipping box".
Amazingly there was no damage.
