Help mother get sons belongings from ME to MD

Hello, I am Jeffrey Snead, I'm posting this for my dear aunt Alison Mcelhany who's been paying 100$ a month storage for her deceased son, my cousin Alex meager things that fit in a closet size rental space. Many may remember he jumped to his death off the coast of Florida on a carnival cruiser moving companies want 5k+ its 1300 miles so the cheapest way is to rent a u haul trailer unlimited miles and drive non stop there and back. This year makes 3 years since we lost our Alex please if you find it in your heart any amount is greatly appreciated. Help me bring this son's belongings home to mom for Christmas ❣
