I looked into indie storage containers, rent or buy, and it makes the most sense for my wallet and situation to buy a 20ft container. Some of those can be rented for 30 days, with their handling transport on all legs included in estimate. If you can get within a zipcode, that should be valid for you in getting quotes.
I really liked the chain boxes, various sizes and services, but, very expensive. the more you don't have to take with you, the cheaper your move. I think the big plus is having the smaller boxes available vs everything being huge. Seems like a good way to categorize your life. um, that was projection; categorize my life ....
I tried to undercount how much stuff I might move and was scared away by prices. I haven't moved more than 10 or 20 miles for 30 years, so I knew it would feel super expensive to me, but it was breath-taking. Miles matter.
I would have liked convenience of hiring movers, but, for me it is too much. However, the rental truck option was very very appealling. Part of that is because I know a lot of out of work concert organizers here willing to labor at most anything, and a half dozen young Amish boys on the other side of it. I would pay all of them, of course, and have a cold cases of water and Gatorade at the ready.
Good luck, there are A Lot of options!! I hope you find a small independent moving company that shows you that they want your business and takes good care of you.
