Start up costs are steep, unless you going to have ten miles outside the city, you going to need a 3-4 acres, then moving earth so storage unit are higher than where you drive car so when you get heavy rain-units not flooded out & ground needs to be slantted toward street then asphalting, you need to build strong units. Yep, I have looked into these good deal. And next place I move to might give this a whirl using unconventional methods.

This is not cheap at all, equipment is very expensive and employees cost big time as well, along with insurances.
One of the very best Small Businesses are Laundromats that only take store only debit cards, front of store has exchange for Debit card unit that only takes credit/debit cards- no cash on premises, you place them in Low Income areas so rents are cheap, have someone there while store is open, people wash their clothes in good times and bad. Another one is advertising truck, it has slanted sides that accept electric signs, drivers go down most roads with billboards on the truck during day and evenings.
I think it best to have "Protective Stops" and owning businesses in my way of not having to depend on income from trading. Start something small and build it up then hire others to do it.
