Go out and get ice block buyers and tell them you can supply to them with quality ice block right where they are. Have a lot of such people and take their orders without collecting money from them. It will be great if they can pay you upfront.
When I started ice block business, I used this model a lot. I will get money from a friend and return it in a week. Before the time of return, I would have made my profit. Since I do not default in paying back the loan, my friend was always willing to loan me the money. That’s integrity. Integrity will help you in the ice block business.
