How to insure shipping large speakers?


I am struggling trying to find an insurer for shipping a pair of 200lbs. each speakers from Milwaukee to Baltimore. Surely many of us here have done this. It is a private transaction, although if there is no other way, we could make it a business (church) to business (hospice) deal.

We can find a shipper o.k., just not insurers (well, one wanted a 3rd party to crate the boxes, but geez, these are Von Scweikerts that come in a plywood coffin for shipping from the factory!)

Any advice would be greatly appreciated. Everyone have a wonderful Holiday!

Update- Just shipped using Yellow Freight and a pallet with excellent results. The pallet was definitely the key - it keeps people from doing dumb things, most of the time.
Just received large speakers shipped by Pilot - no problems. This seems to be an "under the radar" shipper, but they did a great job - apparently several speaker manufacturers use them with excellent results.
fplanner2000 do you have a website for pilot as i have large speakers to ship thanks
