I run into people wanting a flat rate with no explanation of work. There are too many options. Just drop it? Drop and firewood? Drop and haul off? Branches hauled off or no? Do you care about the rest of the landscaping or lack thereof? etc etc. It's just not that simple. They compare apples to cantaloupe. I try to do only what requires my skills and eq. Get some cheap knucklehead to sweep and rake...
