I'd try and get hired on part time with another local company that dies lawn care. It would be sort of like a paid apprenticeship. You'll learn about the business. You'll make money. You'll have off days to build your own business.
This is what I'd do if I were you. I assume you're young with no family/mortgage? Take advantage of this opportunity. It's much tougher to start out when you have a wife and kids.
