employment for a Latin Americanist Historian with M.A. from U.S.A. who speaks Spanish and has travelled/lived in C.America

I have worked in the international shipping business as a Shipping agent. I speak Spanish and have been married to a costa Rican (Tica) for 21 years. Have two daughters with the oldest producing two grandsons. I would enjoy very much conducting international trade with hispanic counterparts. I have lived and travelled throughout Central and South America. My initial interest in the study of hispanic culture was to become a diplomatic liason but I passed the age limit for consideration by the state department (36 yrs old). I would be intrigued with an appointment as an international trade representative or diplomatic officer.
