I'm getting the opportunity to bid a Lowes Home Improvement store for this winter. I haven't taken measurements on the lot to get the footage yet, but if you could imagine it is a big parking lot. We've got two pickup plows meyer and a Swenson spreader a big one that rides in the back of a Ford F250. A John Deere backhoe and a bobcat. On a job like this are you guys doing this by the hour or are you or are you doing it as a set price for a certain snowfall amount. For example 1-8" and 9-13" and so on with salt included in that price. I would appreciate any input on this thanx!
