OK, very old posting but this is what you can be up against. If you want to go big, many large distributors will only sell to store-front operations, no garage or basement shops. They will require a minimal investment of around $5,000.00 for an initial order then so much per month afterwards.
Start small then work your way up as there are some manufacturers that may be willing to work with you. Some of the largest companies at least here in the US started off in bedrooms or college dorm rooms. Find things that people in your country might be interested in, type of power and hulls. Accessories can be cheap and profitable as you're trying to carry everything eventually.
