Collection of Artwork

Over the years we have acquired quite a collection of original works.
Some we bought, some were gifts from people who have touched our lives at one time or another. I cherish them. I even put most of them in mounting board ages ago. Wrapped them well for them to be framed in the future.
Picture framing was a part of my art supply business way back when. Now, after all these years, I have no idea where to get framing materials in or to the area where I live.
Obviously nothing will fit into standard size frames.
While rummaging in my craft room I unearthed them and looked through. Some are still okay. But unfortunately the etching prints show some foxing and in some cases severe foxing.

It breaks my heart and I am very disappointed in myself for not taking better care of them.

I'm afraid the severely affected ones will need professional help. But who ? where ? How to find someone ?
One of the downsides of living in the sticks, I guess.
Anyone out there who can point me in the right direction ?
