We have a couple of customers that want bi-weekly cuts. My brother doesn't want bi-weekly because we r going to have to cut twice because of the length of thr grass. But i'v been reading that in order to cut faster you have to open chute and cut twice anyway. RIGHT? What do u guys think, should we try to stay away from it? How much more should be charged for a bi-weekly cut and what justifies the increse to the customer? For an example, i charge $30 for a weekly, so how much would i charge to go to bi-weekly?
