Do some of you guys bid fall and spring clean ups early? What I plan on doing is putting the mowing, and the clean ups on the estimate at the time someone calls me for a bid to mow. I just take that cost it takes to mow and times it by 5 normally.
Stop guess-timating. Learn how to estimate and make money! $$$
If you are offering the customer a bid for the entire year's worth of lawn care, why not offer these additional services. They can always refuse them if they want but if they don't think of it, they won't say yes to it.
