Hello and thank you for your question!
Fortunately, you are located within good proximity to some great resources for your need. Kansas City is a nearby area in which someone with the skill and reputation you might require can be found. Below, I have included a list of three good contacts. The first might provide a wider scope of who might be known for doing such work in the area. They will not likely be able to "recommend" someone, but instead offer a suggestion, again, of who might be known for doing this sort of highly specialized work. They have a world class conservation department and anything they might suggest would be considered sound. The other two, respectively, are a specialist in paper works who was on the conservation staff at Nelson-Atkins before starting his own service and a very well respected fine art conservator.
Here is the list:
1) Nelson-Atkins Museum of Art(###) ###-####/strong>
Conservation & Collections Management
Senior Conservator, Objects Conservation
Senior Conservator, Paintings Conservation
Conservator, Paintings Conservation & Manager, Mellon Conservation Science Endowment
2) Mark Stevenson(###) ###-####/strong>
3) Van Witt Fine Art Conservation(###) ###-####/strong>
Again, these resources would be considered the best in your area and should certainly connect/ provide you with the service(s) you seek.
Thank you so much for writing in and the best of luck with your important document!
