Hi there,
That strikes me as expensive for what you are trying to achieve. I hired a Luton sized Lorry/truck in June 05, drove it to Amsterdam and packed it full of my mate and his wifey's entire contents of their apartment (furniture, chairs, TV's, all clothes and everything else!) drove it back.
Rental of the truck was £175, Diesel was around £120ish.
So for less than half that quote, you could try this option?! we did it over a weekend too, so got to pack during the day and go out in the evenings!
If you haven't got the time, then you need to ring around a few other shipping/courier places and get them to quote you. you'll then be able to work out if it's the going rate or not
cheers! DtM! West London & Slough UK!
