I ve been int the lawn and sports turf field for 10 yrs now. I know just about everything about lawns you need to know , but im sketchy on how to set up my own business. I have my license to apply the chemicals but what other lchemical license do I need. when do I have to get a business license ? When do I have to claim taxes and what other aspects far as legal should I know. I have my customers and equipment . Just waiting on the weather and some of these questions to be answered .
