We moved house in December last year, we went with professional movers and it cost us a little over $1200 for the entire day. It was an hourly rate and because we had to get packed up and out in time for settlement, they also had to charge us for the downtime in between waiting for the new place to settle.

Personally I would always go with the pros (not that I am planning on moving ever again!). We had 3 guys with one truck, they were so quick, much faster than we would have been. When we got to the new place I kind of expected them to just put everything in the main room and we ferry it around the house. But they made sure all furniture and boxes were put into the right room and it was all done so quickly! This way we were able to do all those little things that need to be done, plus we could easily keep an eye on the kids.

Good luck, hope the move goes smoothly!
