Hi B:
$2500-3500 for your 60 trees is the equivalent to an average price of $41-58 per tree. Let's for sake of argument say each tree has a minimum of 200 board feet (Doyle scale):
$58 per tree divided by 200 BF tree = $0.29 per BF $41 per tree divided by 200 BF tree = $0.205 per BF
I have no idea regarding the quality of these logs: are they veneer quality, high-grade saw logs, low grade pallet logs, etc.?
THEREFORE, I have no idea if they are taking advantage of you, but I do have ONE WONDERFUL SUGGESTION FOR YOU: Immediately contact a professional consulting forester and have them conduct an on-site assessment of your timber before you sign any contract with a logger!
