This is my first year in business, and I was wondering what some of the mowing models are being used. Over the summer, you typically mow weekly, but when does that start and end? Do you play it by ear, or do you have it spelled out in a contract? If it does go to every 2 weeks, what else are you offering? Do you just show up to edge, blow off, and maybe rake in the off weeks, but charge the same, drop the price, or how do you do it?
