I think that the special needs schools will often be private or charter schools. I did a search for “Schools for the autistic”, as I thought that could be an example of population that would benefit from the communication aids, as well as some of the dexterity aids, and found 2 pages of them in the Pittsburgh region. Several of them were chains of schools that may have several campuses in the area or even nationally, I would need to check closer. I just see these as an avenue to large populations that can be assisted with minimal points of contacts.
