Run. I'm just some Floridiot that lives on the beach, but I can't add up 300 plus cord from that kill sheet. Unrealistic Owner, big commitment, far too much at stake.
Here is another argument for not doing this deal, turning it down politely, that hasn;t been mentioned yet. ( I SOOOOO feel like I'm contributing to this thread.).
Why lock yourself into a (really) long term commitment with this one deal, (which is way beyond your capabilities if it is 300+) and have to turn down easier, more productive projects in the meantime?. I mean, Dang, you estimate 6 cord per month, even if you could sustain that, divided into 300+ you're talking 4 plus years. You'll get burned for theft, you got two months he'll be hunting, you'll lose XX amount to rot, lose some more to theft, he'll renege on the deal or his heirs will at any time over the next four years..... Can you honestly say that what you thought you'd be doing now is actually what you planned on doing, four or five years ago?
Aint doin it. Makes ZERO sense, and no dollars.
Did I fail to mention the math aint adding up? His idea of firewood might be the same as some CL ads we see, about the size of a hard prick? Its firewood..... I can see now how he arrived at 300+. Or he is as gullible as he hopes someone else is, and took his "timber manager" blowing cold breeze up his skirt as reality.
"How much can I make Mr. Manager Expert guy?"
"Really?, you're my guy, make some calls and lets get it on the ground, The big check will be good, but I want to squeeze every last penny out of it too, so I'll help by lining up the cleaners"
Run, politely, but run.
Actually, walking is recommended, contentment with making a good decision should be savored.
