$150 per day? I assume you are talking about a logger who has the horses and all the equipment to work those horses in that day. If you were that logger, would you load up everything, go to the site, and unload everything, then say turn right around and load up and go home for less than $150. Probably a minimum of 3 hours a day just moving the team back and forth, given that you were logging close by the barn where the horses would be kept. What I am getting at is just the fixed cost of doing that days work, not counting what you would want to be paid between the time you get to the 40 acre woods and when you want to leave, would be close to $150.
I really think most horse logging is done by someone volunteering their time, and not someone who is in it to make a profit over and above expenses.
I could be wrong, and sometimes am wrong. But think about that $150 per day figure a bit and see if it makes sense to you.
When I was a student, I had a proposal to take on a pulpwood logging operation for the summer. I was being told by the professor that I could just borrow equipment from the local farmer, and all I had to do was get the pulpwood to the side of the road, and piled. I remember having to convince this professor to think in the real world, and don't think I ever did. But I didn't fall for the pulpwood logging job either. It would have been a nightmare summer, to say the least. I had 'zero' equipment.
