Another vote for Two Men and a Truck. We used them when we moved here from Fond du Lac in 2007. Fast, friendly, professional, and only a couple hundred more than we would have spent on a U-Haul truck/gas/pizza and beer for friends. Well worth it, if you can swing it. Plus, we moved early-mid April, and Mother Nature dumped a heavy, wet, slushy snow on us that morning, so I was especially glad we weren't the ones lugging all of our crap.
Another thing that sped up the process was the boxes we used - we bought a bunch of those heavy, lidded accounting boxes with punch-in handles on the side. All the same size, and stacked neatly in the room closest to the front door. The TM&aT guys said it cut at least an hour off the load and unload times (maybe more) because they were so easy to stack on the dollies they brought. What we saved in chargeable time pretty much covered the cost of the boxes and made the process MUCH easier for both us and the movers.
