Armorer needed Midwest

Does anyone know of a Shadow Systems certified armorer class? Or preferably is there someone out there in the Reddit world who is already an armorer. They must be certified by Shadow Systems. I work as an ASO for private aviation and need my pistols signed off by a manufacturer’s certified armorer to be able to carry them. I’m in Iowa but willing to travel a state in any direction to meet in order to get this done. Purpose of the sign off is affirmation that the weapon has not been modified from factory parts.
