First off, welcome aboard the EMT City.
As for your question, take into account that not all EMS services are based in a Fire Department, some are based in Law Enforcement agencies, others are based in hospital networks, industrial settings, community services, and as private enterprises for profit. I might have left a few out.
On this site, there is a lot of discussion, both pro and (mostly)con, for fire service based EMS, primarily aimed at fire fighters cross-trained as EMTs and Paramedics. I mention that, as I am in the Fire Department of New York City (FDNY)EMS Command, and am a mission specific EMS provider in that context. Simply put, I don't fight fires.
What I would suggest, is either look up EMS providers in the telephone book, that are local to you, or call up the hospital nearest to you, and ask where the training might be available nearest to your residence.
