@RM2013 that's totally fair enough, I wouldn't want to drive the van myself, but DH is always champing at the bit to do it for some reason. Think it's the novelty factor.
We've moved quite a lot because of his job, not so much in recent years due to buying our own home, but when we were moving due to his postings the removals companies were always paid for, including packing. I found it much more stressful than just doing it ourselves. They never listened to requests (i.e., this bag is the stuff we need to have when we move in, not on the lorry for 36hrs, please don't pack it - inevitably packed), packed totally mad shit like a whole box dedicated to the bag of recycling we had in the kitchen ready to go in the outside bin, and 2 protein shakers with protein still in them in a box of crockery (the smell after 36hrs on a hot lorry was something else!) There was also no order or reason to anything being packed so it made it so much harder at the other end when we were trying to get set-up. Packing and moving ourselves is cheaper, but mainly means that we can pack in the order we want, know where all our boxes are and what they contain, and unload from the storage container in our own time, rather than being tied to driver hours etc.
I think it's just about whatever works for individuals, though, and obviously if you're packing yourselves then you wont have a lot of those issues. Is it maybe worth starting by totally emptying one room, if you can, and having that as "the box room", so each time a box is packed and sealed it goes into there and isn't in anyone's way? We've done this with our spare room for anything not going to the container.
