can thoroughly recommend 'man and van' people. as a family we've used these 4 times in the last two years and they've been great. i would just say to use a reputable firm though, there are quite a number of 'mans and vans' which only have a mobile phone number and i would be a bit wary of them.
the ones we've used charge by the hour, with a minumum charge (can't remember what it was), and we didn't pay the driver, we were invoiced a couple of days later.
the young, very fit men they employed were australians, as these tend to be the most honest and hardworking we were told.
