I am going to be delivering a bunch of bids tomorrow to different commercial places in my area, I have a couple questions... 1) When to start mowing ( mid wisconsin, i'm thinking about April 15). 2) Do you always mow once a week ( April 1 - November???) or do you start in the spring with every other week, and then as the grass starts to grow faster, mow once a week, and how do you charge them for this, do you make them pay a certain price over the month and go there whether it needs it or not, or just go when it needs it? 3) How do you bill them? by the month? or by the number of times you go there? I've got my "per visit" prices on the bids, and I plan on having some of my bills due in the middle of the month and some at the end of the month. Thanks a bunch!
