Hi all. Been doing some commercial landscaping and really been enjoying it. We are constantly seeing problems with sprinklers. And I’m learning about what companies charge to replace check and install. Was kinda surprised to hear the cost of irrigation. So I’ve been thinking about getting my landscape irrigation license and seeing where it takes me. I’m in Texas btw.

How hard is the test? Someone was telling me it’s pretty hefty on the math use. Lots of gpm conversions and stuff.
what kind of income should I expect?
What type of job should I be looking for?
How hard would it be to become self employed?
