I have two chipping contractors
Chipper would be ideal, but doesn't fit my business model. I'm a sole proprietor and only operate 1-3 days a week. I have two steady chipping contractors that I use. One operates out of the east end of the city, one out of the west.
An hour of chipping costs me $225. If a job requires more than 2 trips to the dump I just work the chipping cost into the quote. I'll often do a small job first and dump the brush (sometimes discreetly) at the second job if I'm bringing a chipper in for cleanup.
This model saves the initial expense of buying equipment, but I also pass along the burden of maintenance and equipment storage space to the contractor (who has to do those things either way). Also my trailer is small enough that I can tow it will a mid sized SUV and it parks nicely in my city sized driveway. I just have no need for a half ton living in the city, did it for years and it sucks.
It's not for everyone but this setup is very efficient for the type of work I do.
