I have owned a commercial landscape maintenance company for 20 years. It all boils down to the specs in the contract ...
To get reliable service the operator needs to make between 35-50 per hour. A standard 1/4 acre lot takes approximately 30 minutes for a basic cut with 2 people on the crew. That means you should be charged 35-50!per cut.
To keep a neat lawn in Jax, you need to be doing 42 cuts per year on average. This can change depending on climatic conditions for the year, but if I were doing a contract, that would be my maximum number of cuts per year.
Bear in mind that Aprill through September require weekly visits and the "winter months" will require visits every 2 weeks.
Do the math at $35 per cut: $35x42= $1,470 per year. Convert that to months = $122.50.
Anything less you pay, you are asking someone to live below minimum wage standards. The will certainly not be able to afford an AR, much less an eotech or Aimpoint ya'll isist on. They probably won't even be able to afford ammo.
20 years ago, I used to do residential lawns, but it's funny how people want the best service but don't want to pay the dude putting in the sweat.
Ask yourself, do I want reliable service ... Then don't pay less than what it's worth. $125 per month minimum for basic mowing service :)
