I have been working in the green industry for over 6 years, and this is my first year owning my own lawncare company full time and its going great. However, I'm finding that bidding residentials is a cakewalk, and bidding commercial is a huge complicated headache! I'm basically looking at the commercial jobs a guessing how long it will take and charging 60 bucks and hour. I know this is going to get me in trouble, and I'm wondering if anyone has any generic formulas for square footage that could at least get me on the right track!?
