If successful, they can generally make about $70,000 to $100,000 net income/profit for the owner per year. But then the idea is you can expand without too much trouble once you have the first one down pat. So instead of one, you now own five and you're making $300-$500,000k/year. The one I'm considering requires: - $30,000 one time fee. - I then pay for all the equipment, supplies, etc, like any other business. - I have to cut them a check for 5% of the total gross sales as a royalty fee. - add another check for 3% of gross into a "marketing fund" which is suppose to pay for advertising, promotions, etc.
