Whoa those prices people are sharing are steep. We moved 2 queen beds, a dining room table + 12 chairs (taken apart) and most of a house 400 miles and did most of the packing ourselves with a small amount of help for cash we found on NextDoor, maybe $1200 total but it costs time to pay less. The biggest expense is labor in being unprepared and having workers do it for you or to wait for you to get organized.
Pack ahead of time, which I did slowly doing 5 boxes a day - writing with marker what was in the box and lining the perimeter of the place with boxes which I only sealed the day before leaving. From
Amazon medium moving boxes with handles pack of 20 - 18"X14"X12" - Cheap Cheap Moving Boxes.
Throw things out as you go along, throw a lot out so you aren't paying for junk removal.
Uhaul town to city was around $400, I would suggest you do not pick any time around college move in or move out or you'll pay much more if you ever get the vehicle, they will cancel without notice if the truck is late. I wanted a van but they seem to keep these in town so I got a medium truck. Reserve it ASAP, cancellation was free for us so I booked a few that I canceled when I was sure there would be no storms.
We got the truck for a few days extra in case of bad weather. Day 1 we packed it, morning of Day 2 we packed it and scheduled help for late in the day - $200 cash for NextDoor workers. Day 3 we drove, or I should I say I drove because the seats are tough on a bad back and my back is better than DH so he followed in the car for safety, he stayed behind and if I turned on my blinker he got over first and gave me room. It wasn't too bad but I needed a pillow to see the mirrors properly since they don't move up and down so be warned if you and DD are not tall. For 900 miles I might spend the night somewhere because you can't drive fast in these things- have a lock for the uhaul. We kept the vehicle the day after getting there to have wiggle room. Day after driving we unpacked in the morning and had help late in the day after we were done for $400, this was more expensive in the city area.
I kept furniture because it was expensive and I had a lot of stuff to move in boxes anyway. If DD can drive back and forth a few times to a storage locker in her new town with a car full of boxes she can probably sell the big furniture and avoid some of the costs and annoyances of a big move, including the stress. Many storage places have great intro deals so she can get stuff to the new town ahead of the move in date then move her things into her new place slowly. Just know when picking a place read reviews for reports of vermin, I looked at a few and some were disgusting while some were spotless... the reviews will tell you.
