Looking for Mustang Nation Help - Collectables

As I am now retired, I am looking at interesting stuff from 15 to 30 years ago, in my storage closet in my office.
I would like a few trusted people that know something about stamps. I have Russian stamps from 1865 to 1921 and then up to the 80's. The same with Ukraine, Poland, and most of eastern Europe.
Are any of you educated in stamps? Do you have a trusted shop you could refer me to make an appointment?
Thank you in advance for any guidance you can give.
We better with the conference this year.
