having capability to move trees and lumber and storing, drying lumber is as important as being able to mill a tree into lumber. there used to be a sawmill on my property and the structures to dry and store the lumber take up much more space then the structure where the actual sawmills were. its a great way of life but is very physical work from what I understand. as far as income streams selling lumber of
course and milling trees into lumber for people who bring their own trees to you. but the folks that used to live here went a step further and build a large woodworking shop with all the basic craftsman power tools, planer, joiner, router, saws, drills, sanders and would build all sorts of stuff in bulk from knick knacks for tourist shops to bird houses and bird feeders and cedar chests too.
good luck and success in your endeavor
