I sell around 125-130 cords most years on the side from my main job which is teaching. It gives me the summer off to stock pile and get a large percentage of my wood processed. During the summer I hire local teens (some work out and some don't) to help with splitting mostly. I deliver that all on weekends from mid September through early November. On those days, I have a kid helping me load (all done by hand, thrown loose in my dump truck) and he splits when I'm out on the road. I don't have the equipment the OP has but my operation takes up less than 1 full acre of space on my moms farm. I use 2 chainsaws, 1 TW6 log splitter, a John Deere with forks for moving logs, and an f350 to deliver. If I sold all of my equipment (and I couldn't sell the tractor because that belongs to the farm not me) I would have a hard time getting $15,000 for it all.
To the OP, I see you posted your logging equipment, but what do you have for firewood processing equipment?
