My brother in law lucked up and found some great old school doors with etched glass numbers on them every door is different but it adds to the charm of their cabin.

If you can get away and go to Brimfield, MA http://www.brimfield.com/
Huge array of stuff. Find a dealer that has tons of doors or windows and make him/her a cash deal.

These older pieces are usually of solid wood and built a million times better than some of the stuff on the market today.

There are tile outlets all over the place as well. We have a great flooring place here in Atlanta called Floor and Decor.

I bought some 16" slate tiles for a little over a dollar a piece, home depot wanted over two dollars each.

Is there any old barns or buildings on your 200 acres? If so have that wood recycled and planed down if it is warped and use that for flooring, siding or roofing. It will give you that true rustic feeling.

Good Luck!
