The containers sell for $5k to $8k each depending on size and condition. Maybe just sell them for $1k each and buyer has to agree to deal with what is in them?
Not if you’re “renting” them from the liner. Then depending on the port, it could be an astronomical fee per day
What I mean is, if you want to buy a shipping container, they cost $5k to $8k (used). People buy them all the time. If they were doing this in about 9 months from now, I would take some of them off their hands. They could sell them for much less to get rid of them quickly and stop paying the rent.
