We've always moved ourselves, for he cost of $200 for a truck, and $100 in fish'n'chips and beers (for mates).

Never had any significant dramas, but it's always been on a shoestring ...

If the money wasn't a big deal, I'd get the professionals in, and (if the move wasn't covered by my home & contents insurance) Id do it with insurance.

If the money was an issue, I'd get the truck, and do it ourselves, with as many mates as we could feed.
