Chicago area expert to restore antique embroidery?

Hi, my real name is Dana and this is my first time posting on this forum, I'm usually over in the gardening forums. I live in the Chicago suburbs and I recently inherited a piece of antique embroidery that was originally a chair seat or back. I'm pretty sure it's over 100 years old and possibly quite a bit more. The stitching is very delicate and some is starting to come out; I'd like to get it repaired/restored before I reframe and hang it. I have no idea how to even start finding someone who could do this kind of work. If anyone has any leads I'd appreciate it! Thanks!!
