I've found that "people" have all sorts of wild ideas of what something is "worth" without every actually trying to sell what they are so "knowledgeable" about. When I bought my land, I heard from just about everyone that I know in how much money I could make off of the different trees on my land. Pines where worth so much, but then all the hardwoods are worth so much more. I spoke to a couple dozen loggers and never had a single one come out to my place. Nobody was interested unless they could do it their way, and I think a big issue was that I live on the land. That seemed to be the biggest deal killer. I then went to three places that buy logs and got prices from them if I brought the logs to them. They did not want pines, but would accept hardwoods if they where big enough to make railroad ties. Big demand for them, but not worth the effort for what they pay.
Then I went to a guy who advertised on Craigs List who wanted to buy trees so he could mill them up and sell the wood. Again, it wasn't worth the effort for me to deal with him. I know of 4 other guys milling logs into lumber, beams and mantles. To me, they are selling the cut wood so cheap that it's not worth the effort to sell them logs. I base this on what I make going to work, and what I would make taking the time to cut down and haul the logs to them, and then the time it takes to come home. I figured that when it was all said and done, I would make less then $10 an hour, and that's if nothing broke down, got damaged or created other issues.
I found the same to be true with selling firewood. There just isn't any money in it after you factor in all the time it takes to get it ready to sell.
