Make sure you document what's being packed and stored. Friend of mine did something similar, had moving company pack everything in his house and stored it for six months. When the shipment was finally delivered to his new house, all the good stuff (an extensive tool collection) never made it. I don't remember the details, but since there was a long time between packing and unpacking and I think the storage place was separate from the moving company (a lot of finger pointing), he lost with no recourse.
