If you go to a Budget rent-a-truck location, they can probably give you the number(s) of guys that only load and unload trucks. This saved me last moving day. Also helps if you move everything to the room closest to the exit door. Finally, hand trucks are great as are floor dollys (medium and small). Not too expensive.
P.S. when packing amps, preamps, DACs, etc. always put the front in first (into the usual big plastic bag). If you don't, there's a chance you could scratch the front, cutting the tape that is sealing the bag.
