Sorry for the late reply!
Yes I actually have some quarries/mines and objects and buildings that I could arrange into logging operation assets. I plan to eventually release them or can even send them to you early but it would be helpful if you could suggest what form they could take, so I know what you're expecting. - such as reference photos or logging mill graphics from other games. I wouldn't copy them exactly, it's just that I'm not very familiar with these kinds of buildings.
