Hey guys, I currently only cut grass but would like to get into installing/servicing sprinklers. I know the best way to learn would be to work for someone for a few years but that is not an option for me. I am a school teacher who has my business on the side but would love to go full time someday doing sprinklers along with the mowing. My question is, have any of you or your employees gone to these training classes? Are they worth taking a week off of work and spending money on a hotel and possibly airline tickets?
