I didn't really get that great of a fist season this year as I've had alot of health problems (at age 18 great!) so I'm just saving up money and getting ready to do alot next season. So I wanted to get some information on how to get commercial accounts, how to give accurate estimates and stuff like that. So is there any good information courses or something to that sort about lawn business out there? I'm still in high school but I'll be done in the winter so I dont think i can go to a college or trade school. Any one have some websites or something for me?
