We moved once and packed ourselves. Pre-DC, still smashed broke and relatively newly married, and had both time to do it over a few weeks and space to put already packed boxes out of the way.
Also, in that first house, we tiled walls and floors ourselves, set out the garden from bare earth, painted all walls, and did all sorts of work to make it both habitable (from bare walls new build) and cosy.
Nowadays, we have 1 DC but with HF SNs, far busier jobs, and a far more cluttered house (almost 20 years of conjoined lives built up). We no longer do many of those larger DIY jobs ourselves either - we have been getting painters in every few years, and getting builders to do the extension projects without leaving us elements to do ourselves.
And other than our own experience, I have helped to move my DUncle on a good few occasions. He is forced to DIY the move (diocese won't pay for packers, only just about pays for movers and lots is moved by extended family in cars). And he does a LOT of pre-packing and organizing as well each time, every few years, and knowing in advance that it will happen so he tends to keep decluttering over time too. The only time he could get movers was when he was sent overseas - as it had to be container packed.
It really does make so much difference to get the movers to pack as well, if you can afford it. Especially if there are any small DCs to work around.
And if DH doesn't want to spend that money, then you can be in charge of keeping the DCs out of the way while he and his family get stuck in (and don't break anything precious, and don't forget anything important to you either!).
