Stop in for a cup of coffee

So good idea or bad idea?

I have several big trees I’ve had to cut down where I’m building my house and several more that got uprooted in a delrecho. Trees are mostly ash, hickory and beech. Most are 30-50 ft before the first branch. Hickory’s are nearly 4 feet in diameter. Wondering if I can find a saw mill that will cut them into boards for me and I could then build a garage like they used to build barns, with wood board sides and if that’s be any cheaper than buying pine lumber ?
