When DH was in oil, we were moved by the company once a year. I never had a bad experience, myself. The worst was that they'll pack EVERYTHING including the trash, unless you really watch them. Plus stuff gets labeled so generically : "Kitchen". So is that your everyday silverware, or the cake platter? Grr. I did learn a lot about packing from watching them.

Slightly OT. Most movers have a "u-pack' option where they just load/unload boxes and furniture, and the homeowner does all the packing. This can save a lot of money if you have the time or inclination. On our last move,(non company, cross country) they underestimated our weight by about 10,000 lbs but we didn't have to pay for it because of the fixed coast estimate/contract.
