Perhaps you could supervise the "professionals" and give them guidance to pack your things (not sure if that' an option in your situation) or if DH is worried about it not being covered under insurance if they don't pack it, is it possible to move (depending on the size) of your stash and machines in your car? If you do this, please notify your insurance of the value of these things (learned the hard way with my daughters wedding dress, in an accident 6 minutes after picking it up).
