Happy to help. I sincerely feel bad for anyone who is a victim of dishonest dealings. Actually, I'm also angry that these things happen and give the rest of us firewooders and even professional arborists a bad name.
Lots of "firewood retailers" are tree service professionals who have to pay a dump/landfill to take their brush, logs, and stumps, so they take some of it back to their processing yards for c/s/s (cutting/splitting/stacking) and later selling as firewood. They certainly are not going to pay to take wood.
The rest of the firewood scroungers won't pay for wood unless they are desperate. This usually means that they burn wood to heat their homes and have run out before the end of heating season. Only then will they pay to get processed and seasoned firewood. Some will pay $10-20 per pickup truck load to cut treetops from a timber harvest, but that is also rare.
Another thing working against your getting any money out of your tree is the season. There are plenty of other homeowners who have winter/spring blow downs that are willing to give the wood away just to get it off their lawn. You are competing against them in the marketplace.
