I have moved about 15 (including one across the country) or so times and have it down to a fine art. I can pack Thursday and Friday, help the removalist (mostly by pointing) load and unload on the Saturday, and be moved in by Sunday.
Until the last move a few months ago. Settlement on the new house got held up. So instead of settling on Friday, moving over the weekend and handing the rental back on the Wednesday, we got to move all our stuff (excluding a mattress and a fridge) into storage on the Friday, and camp in the rental until the Tuesday when the settlement went through. Dodging cleaners/gardeners the whole time.
Then we got to move the mattress and fridge to the new place and camp there until we could get everything else the next weekend from storage by ourselves with a hire trailer. We couldn't afford 2 lots of removalists. Both DH and I were working full time during this too.
Honestly, it was the worst move we ever had. So my tips for the OP are:
1. Leave plenty of time for settlements - have at least a week of overlap. Not too long though or it will just seem never ending.
2. Hire professional cleaners for the old place - so much easier than coming back and doing it after you have spent all day moving.
3. Have an 'emergency crate' - Toilet paper, dish cloths, a set of plates/cups/cutlery, kettle, coffee/tea/pet food/sheets for the bed on the first night
4. Hire movers!!! Can't stress this one enough
5. Purge and clean as you purge stuff
6. Have one little box for your TV remotes/ tv cords/phone chargers/ipad charger/e-reader, etc and have this in the car with you.
7. Pack dishes/fragile items wrapped in your linen and clothes. Much less mess unpacking than newspaper
I am sure there are more tips, but I think they are the main ones...
