I've been doing lawn maintenance for a few years now part time and have the client base to jump into full time at the beginning of next season. One question I consistently get asked is "Do you also do irrigation?" Obviously that is a good sign so I'm going to go ahead and get a license for it to expand my business in Texas. I was wondering if there is a study at home class I could take that may be cheaper than the 40 hour class. Ive searched and didn't find anything, so in a last ditch effort I figured I'd ask you guys and gals. Thanks in advance, Jeff.
