I used Dumbo movers on the recommendation of a fellow friend of mine. They do not charge hourly.I have used them twice so far. Never a problem. The fee is per item (IE one mattress, 5 large boxes, etc) One both occasions we ended up with more boxes (usually my records) than we had projected and they let it go for now charge. They also have a storage facility in case your move out and move in date rent within the same day. If we were moving a third time I would use them again. My friend used them at least twice. No problems. They were careful with our stuff, records and equipment, baby crib, etc.
