Buy the saw, buy another as backup, repair saw, replace chain and bar, furnish truck to beat the crap outa, repair truck as necessary, gas and oil for truck and saw, buy wedges, mauls, sledges etc etc. Have tractor to drag logs out of the woods. Then furnish a place to stack and store wood while it drys. Then there's the labor, cut the wood, split the wood, haul it in and stack it, and cover it then when dry, load it up, haul it and unload it. Pay for insurance and property taxes. Bear in mind the unemployed guy down the street needs money so he's out cutting and selling firewood, undercutting your prices. Then your supposed to keep track of your sales and pay the state its share of sales taxes and timber taxes. All this and just hope you don't have an accident and get hurt.
I own 20 acres of alder, ash, maple, fir (which I rarely cut), and hemlock right in my backyard. Dry wood around here goes for around $165/cord in the summer to around $200 in the winter. I cut and split (by hand) around 10 cords a year. I sell 4 or 5 cords but I think I'd be better off paying my customers to buy their wood elsewhere.
If I didn't simply like cutting wood and enjoy the exercise (its cheaper than Golds Gym) I wouldn't do it. Unfortunately I'm hard headed. How the heck do you guys make any money cutting and selling firewood???? My hats off to ya.
