One company wants me to right it up as a seasonal contract. what month do you stop doing reg maint mowing and start the fall cutting. Am I making myself clear? april 15 -??? is reg maint at such and such price. Anything after ??? month is extra. Take in consideration i am in western NY near buffalo.
