How much does a cord of seasoned oak split cost these days? $250? $400??
Let's assume that those rounds are cut at 18" (18*150)/12=225 foot. Let's also assume that they were roughly two relatively large oaks, say, 100' tall or so. Seems a reasonable height for a tree that has a base upwards of 36".
the last time I cut up one large oak that was about the same height and width of one of the two I'm estimating — I got about one cord of wood stacked. For simplicity, let us assume that what is there is two cords of wood once split and stacked. If we err on the high side of a cord of oak already split and properly seasoned ($400) — so $800 for two cords already seasoned and split, compared to $1,100 for "seasoned" rounds (how does un-split oak season as a round???) — plus you are required to haul it away, then split it, season it, and stack it. You're basically paying this person an additional $300 for maybe two cord's worth price — to do most of the work, time, and effort in actually processing it into firewood.
Seems like a s**t deal to me, but what would I know, I get all of my wood for free. Free is a relative term, as there is a cost for everything, like my time, effort, equipment/fuel, etc.
