We got the idea from a couple of American friends who had spent some months living here. When it came time to go back they had amassed furniture, air conditioners, motorcycles, etc. and could do nothing but either sell them or give them away. If it became well known enough between say Puerto Plata and Cabrera there might be enough business to support it.
My problem from a business standpoint was that it required a high initial investment, not just for the land, the buildings, the insurance, the security, etc. but also for operating capital to keep it running while you built up clients to the point that it could be self-sufficient. There's no way to 'ease' into it. I prefer business models that allow me to test the waters and the expand using the profits. Can't see how that could be done, so you'd be very dependent on really doing your homework to know exactly what potential customers are out there. That also, is very hard to do down here.
P.S.
There also seems to be a cultural component because folks here, even transplants, seem to not value possessions as highly. Not like in the US where we buy our stuff and then have companies to haul it all across God's green earth for us.
