I owned several timberwolf sawmills,as well as sold them throughout eastern Canada and the USA,These mills were top of the line fully loaded,and competed with woodmizer. I own over 200 acres of woodland,and at the time a 230 timberjack porter,and a massy 50 loader with forks,nyle dry kiln;the best move I ever made was to sell it all except for the woodland. I had one mill set up on my property,and one mill I used to take to various sites to do custom sawing, I soon discovered that many people had no idea what a saw log was,ie small logs,dirty muddy,not straight,full of worm holes,etc. I started charging by the bf,.25 cents a bf. based on what the customer wanted,was usually told that they wanted 2X 6,8,or 10,and 6X6 in other words heavy timbers,but when on the site customer would say he forgot and needed 2000 lin feet of 1X3,and 500 pcs of 2X4 which as you know takes a **** of a lot longer.
Now for the mill that I had set up on my property,we averaged about 2000 bd feet of lumber a day,2 of us me sawing and a helper,of course some days cut 5000 bf if cutting 6X6 and some days way less than 1000 bd feet if quarter sawing hardwood. When it was all figured out at the end of the day I was working for about 5 bucks an hour;and that doesn't take into account the time spent to sharpen bands normally about 2 hours every evening. Than the down turn in the lumber industry,people could actually go to a larger mill and buy lumber for less than what it cost me to cut and get my logs to my mill.
Now its not all bad

if you have axcess to good pine logs or good quality hardwood you may be able to make a $ provided you can find a market for your finished product,there are several nich markets out there,just do your homework and get all the info that you can get and good luck
