I don't like the sound of two things:
1) "I chose lawn care because it was so easy to get into"
2) "I know a lot about/enjoy the business side of things"
These two statements do NOT go together.
did you actually DO research in the green industry?
what do you know about lawns, turf, chem, weeds, machines?
how did you get any training?
do you think we are all just guys who push mowers and there isn't anything to it?
I would STOP right now, don't cut a single lawn more.
Spend some money and TIME researching a side business and not just go for one you "believe" is easy entry, because you obviously know very little about what you have chosen to sink time and money into.
