You may want to do a search of the message boards for Movex. There has been a lot of discussion about this company, and frankly, I am considering using them for my own move.
Another company that we've heard a lot about in the You Pack We Drive arena is ABF. You may also want to get a quote from them so you're looking at "apples to apples" for your YPWD quotes.
Also, since these companies both quote by linear feet, its important that you have a good idea of how much stuff you have, read: how much space you need. There are others that post here, that may be able to give you a better idea of that than I can.
If you do use a YPWD, I personally would be very interested to hear about your experience when its finished. My move is tentatively set for late February, and I have not yet selected a company.
