Have you taken into consideration insurance needs?
I've done plenty of productions where it was a handshake and a "don't worry" and never had a problem. But in the long run, you want to protect your finished product. So a policy that would cover shipping, use of the puppet and catastrophic loss would be worth it, I think, when dealing with people you may never have met in person. If the agreement includes a stated limit to the value of the puppet in case it is lost or stolen, that would help too.
Just tossing out ideas.
