I'd look around Holmes and Wayne Counties. We vacationed there earlier this summer. About every third or fourth Amish farm had a cottage woodworking industry. Also a number of decent size factory fabricators. If you have trouble tracking them down, give a call to Keim Lumber in Charm. They are a big supplier. You might also call Baird Bros. in Canfield, OH. My sister used to work there and they do a lot of custom millwork.

I am in northeastern Ohio, and in need of a new source for various simple wood products.
I have been buying assorted reproduction replacement items, such as oak rocking chair runners, highchair trays and arms, and oak hiphuggers for chairs, from an out of state supplier.
I would like to find a closer, more reliable source
