Engine Shipping

I'm looking to get a good deal on a private seller of an h22. Have any of you ever shipped an engine? What company did you use? How much did it cost?

I also need to have some secure way of sending. I don't want to wire this guy the money and have him run with it, and he doesn't want me to run with the engine when I see that it's shipped. You guys know of any way to handle this?

Prompt response is appreciated, thanks.
