Greetings Richard:
Yes, I would certainly say that was an incredibly ridiculous offer as these trees, even if they were all firewood-quality trees, would be worth at least double that amount, at the the very least (i.e., a face cord of seasoned oak)!
I'm glad you've decided to forgo that logger's insulting and seek the timber sale administration services of a profession consulting forester -- you absolutely made the right choice!
Kudos to you for doing your research!!!
