As someone that moved out around your age it irks me a little to hear about parents looking down on their kid like that.
I have a feeling that after, say, 2 weeks of work, the OP will have a better understanding about the landscaping business than his parents, and should therefore take much of their advice with much salt, as it will be he, and not they, who will be the professional. 😁🙂
