We moved from Richmond VA to Laconia using PODS in 2009.
The timing was about as your plan, we visited this area in March 2009 (stayed at the Fireside Inn), bought a ranch house in South Down, and are very pleased.
We packed one PODS in February to de-clutter in preparation for the sale and put it in storage in the Richmond franchise facility.
Packed 2 more full size and one smaller one in May. They were all shipped together to the Nashua franchise facility, then trucked one at a time to Laconia until all were in the driveway.
We hired a packing company to load them in Richmond and unload here. (one day each end, saves a lot of heavy lifting and they know how to load. And then the PODS are not blocking your driveway too long.) They were one of several referenced by PODS: Pack and Load Service
http://packandloadservices.com/.
They supplied the moving pads.
But we bought the shipping boxes online (
http://www.usedcardboardboxes.com), and also found Home Depot with comparable prices for moving boxes and supplies.
We selected PODS as they were one of the few such companies that serviced the Laconia area and also our origin, Richmond. There were some companies that would only cover southern NH, or did NH but not RIchmond. Depends on the franchisees.
The PODS never leave the PODS system, but I would expect that you could arrange for storage in the Nashua facility rather than leaving them in NJ.
