Honestly i would go for a church/sect. I have friends and pardon me for religious people here but it is tax free. I can profit but i would also help the poor and give free services and shelter to them. I think its a sustainable income and with correct processing.
It can be nice solution but I do not think it will provide you profit, it would be more considered as a non profitable organisation if you are asking me.
I would most likely start a couple of clubs and restaurant that are accepting the bitcoin but all with a unique theme.
