You'll have to note the "probably" in that statement. So, it turns out that you have c/s/s 20 cords for several years. Didn't know you were doing this professionally. If that is the case, then I would expect you to c/s/s WAY more than 20 cords a year. I would almost expect that on a monthly basis. Around here a cord of hardwood runs $220. At 20 cords, you would only be making $4,400. A little tough to eat making just that. I would have to do about 230 cords a year just to justify doing this for a living part time and at 230 cords a year it would seem like a full time job. Honestly, I have no idea how anybody can make decent money selling firewood unless they really have the machinery set up to process it quickly and a ready supply of wood delivered to their place of business. Guess my statement should have been "The difference between you and I is that you probably do this for a living and for charity".
