I have a friend who started a lawn business..
I have always liked installing lawns from seed, all the sprinklers, underground pipes, valves, etc., so I helped him get started because he knew not much about this field.
He eventually got a business started and kept at it for a long time.
Once I did his route for a week while he took some time off.
Holy Cow ! That is a lot of hard work when you are doing a bunch of these lawns every day.
You have to be very deliberate, fast, and able to do everything with one pass..
Heck of a hard way to make money unless you can grow it big enough to have commercial accounts..
Then the hardest part is the accounting, equipment maintenance at a much larger scale, managing lots of people, workman's comp, insurance, etc...
Whenever I think that Detailing for a living is really hard, I think back to that year that I worked with this good friend and am so glad that I didnt get crazy and want to partner up with him on this..
