How can I turn my passion into something which benefits and provides a service yet generates income for me?

My passion is gym/fitness/bodybuilding/powerlifting/nutrition and I am currently 24 years old and I have good strength in the gym and a good physique for my 6ft2 frame. I love to lift weights and would love to turn this to something like a job for me. I dont have any specific fitness qualifications and Im not intending to go for them either as my first hand long experience with my passion is far greater than a certificate on paper. Is they any ideas that can get me in the right direction and hopefully take off?
Spelling error above: Nutrition in the list

Start a neighborhood gym that is very small. Only 5-10 people can fit in it. And all of them get super-personalized attention. As if they were all celebrities. People would pay a lot of money for that..
