Hi OP. I've done a few moves. I did a 1200 miler (actually RT, turns out it didn't work out). and two local (100 mile) moves in the past year (oh boy, I know).
Anyway, going North 1200 I did a Penske truck (16 footer) and hired moving helpers (movinghelp.com). BTW, Penske's trucks are much newer and more reliable than Uhauls. I've never rented one with over 9000 miles on it, so they are very new and in great condition-always clean. I am a 23 year old short female and found that it drives much like a van. Going South on the return it was much pricier, so I went with a full service company, but with was only possible because I received a great discount. I have
AAA and they offer a 60% discount with Atlas. They transfer from a little truck (due to difficult to navigate apt complex) to big to little truck. I had one lost item and a damaged item, which I claimed. They were great with p/u. Their delivery contractor left a lot to be desired. I can look up my cost if you'd like, just let me know. One thing to keep in mind is that it took two weeks to get my stuff and I had to be available at any time during those two weeks to receive my items. If she's starting a new job this is not at all practical as the moving companies will NOT work around your schedule, no matter what. If you can't receive, they dump it in storage at your expense. This was my experience at least. Other full-service movers were extremely expensive and pushy.
For my two local moves I went with Penske and the moving helpers. I read the reviews for the moving helpers and usually pick something mid-range in price point with high reviews. I've never had anything broken or damaged-even antiques. Some of the moving helpers are better than others, but this tends to be the cheapest way to do it for me. Just depends on the time of year and direction you are traveling though.
I see your from KS. Central FL is about 1200 miles-any chance this is where you're headed? If so, I can recommend some moving helpers in the area if that's the route you decide to go. Let me know if you'd like some more specific details on my experiences. I'm happy to share. I find moving extremely stressful. I'd be happy to alleviate some of that for you if I can.
