My neighbors have a 'full service' lawn care company that mows, trims, edges, fertilizes, pulls weeds... etc. They don't do sprinklers because i had to help them figure out a problem and find somebody to fix it (because it was more work than i wanted to do).
Also, While their lawn looks 'OK'.. It's not great. It's currently a nice green-yellow due to the heat/overwatering/being cut too short (while mine is nice and green... because I care more about my lawn than some lawn care worker (super nice guys.. I've talked to them.. at least the ones that speak English 😃 ).
If you end up finding a company that will 100% take care of your yard... you are going to end up paying $$$ (but i don't think you'll even find a company that will do it)
