There are two tree services that I know of within a mile of me. Not sure of their pricing, but had heard $300. per cord. Quality varies, meaning cut length and split size. I do not see stock piles at their yards, but may have more than one yard that I'm not aware of. A third person clear cut 20 plus acres. His is cut and split in huge piles and was charging $300. a dump trailer. Guessing it was a good cord, but have not seen his trailer loaded by the road this fall. Word is he is putting up storage units on his property.
I do know my customers bought elsewhere last year, as I was not selling firewood, and many have called back and purchased from me again. I cut 16" length on a log deck, split fairly small for handling, good stacking and season one year, some of it covered. It's pretty nice stuff.
Along with 6% sales tax, I use pallets, Posch PackFix and netting, and 6' x 6' covers on the top row of pallets when double stacking. Each of these add up in cost that come off the top. Pallets and covers get reused of course. Covers last two years and UV breaks them down. They tear like toilet paper in the dotted line. Pallets last three or four years if hardwood. Some less due to damaged top boards from initial firewood splits dropping 7' off conveyor.
Delivery is by far the most costly expense. Firewood is supplemental for a tree service and their trucks. For me it again comes right off the top with a dedicated firewood equipment. At $300. plus delivery, I'm not making much.
