I moved 8 times in 8 years, and have moved 11 times total, here's my advice:
Main thing with a move is to get your crap all packed/boxed BEFORE you "move" it.
If it's all ready to go - packing can be done over many days/weeks in advance... when you actually make the act of transporting it from old locale to new, it's fast and easy.
If you do that, then renting a U-haul becomes easier as you know how much stuff you really have based on number of boxes...
...OR, if you are using your own pickup and some friends, you won't waste valuable time packing, and your friends (who tend not to be good for more than a few hours in many cases) will be most maximized this way.
Here in the UK, I would scour the local paper for adverts featuring "man with a van". You'll get some muscles to help shift your stuff and amusing conversation en route.
I did make the mistake a long time back of hiring a Christian van with 2 men, because I thought it would be good to support the organisation since it did a lot of work helping druggies. Spent a 2-hour journey with hymns on the CD player and constant efforts to convert me -
I like to take my moving as a chance to organize and dispose or recycle. I like the idea of the moving comtainer dropped close to your door. As you organize you can move it out of the equasion but it sits under lock and key. They normally give you 3 to 4 days to do your move. It worked for m several times now.
