So to become a "professional" Martial Artist, you need to basically
get paid for martial arts related stuff, correct?
"Owning a school is one way" - - Professional Business-person/School Owner. Not necessarily a "Professional Martial Artist."
"hosting tournaments could be another way" - - Professional tournament host/promoter
"maybe supply manufacturing or selling." - - Professional retail
"security consultant" - - Professional Security Consultant with a Martial Art background
"stuntman" - - Professional Stuntman who also knows some Martial Art.
None of the above are "Professional Martial Artists." They are other Professions where the individual might utilize Martial Art skills to better perform the job, but each could also be done without the Martial Art.
Any of the above mentioned jobs might also be enhanced if the person is a skilled
wrestler, but that does not make them a "Professional Wrestler," thank God!
There are many options (some already mentioned), but these are professions other than the Martial Art, which involve or utilize your Martial Art skills as a tool within that profession. Just like being good with computers might be a plus in many professions, but that does not make you a professional computer technician unless you are specifically employed as such.
In my opinion, the only "Professional Martial Artist" is one who either solely
teaches the Martial Art for pay (self employed or hired; Full time or part-time), or
performs and demonstrates their Martial Art skills for pay. An actor who demonstrates Martial Art skills in fight scenes is a "Professional Actor" with Martial Art knowledge as a talent on their resume'.
How can one make money being involved in their art as their job? Any ideas?
There are many options (some already mentioned). Here are some that come to my mind of how to use Martial Art skills in
your chosen profession:
Security guard
Security guard trainer
Firearms instructor
Bodyguard / Executive Protection
Private Detective
Law Enforcement
Probation Officer
Child Protective Services
Jail or Prison Guard
Military
Movie Film Industry: Actor; stuntman; stunt coordinator; fight scene coordinator
Bounty Hunter
Automobile Repo
Jerry Springer Show
etc., etc.
I am sure there are a few more!
