Just by reading here, i would say stall small, or go big, nothing in the middle.
the other thing to consider is you can't just start now, you have no dry wood! You have to cut and process and let it sit for a year beore you can have anything worth selling. You'll have a lot of time and expense involved before you see a single dollar back. Logs cut this year and not processed are not good to burn.
The other I have read here is custom wood, sold by the bundle, for campers and fireplace ambience burners, which is much more per cord, but more handling. And also find real steady guaranteed customers like the pizza joints and home burners with big demands and you know they got money.
What the other guys said, if you can guarantee to take delivery or pickup tree service wood, you would be miles ahead to start out like that. Not near as much equipment needed right now, just have to get it cut and split, then start looking for that dumptruck or trailer for next year, and start looking for customers as well. Who knows, some might take green for next winter, but I doubt that market is near what the "need it now, must be seasoned" market is.
hey, good luck!
more edit, dang keep finding more typos and had another thought...
I think if I was going to do it...I would try to make an asset out of the liability of the grade C wood. The uglies, lesser species, off cuts, gnarly stuff that you will accumulate while processing. Chunks of wood that would be near impossible to sell, but still could be burnt. Anything, even pine, which I bet you could get for free all the time where you are. Build a kiln for the good stuff that will be sold, and run it off the uglies/everything else. Just being able to advertise "kiln dried" wood would set you apart from the other guys in your area. I would still open air season by bulk, then, by demand, on a sale by sale deal, do a final kiln dry for those cords right before delivery.
