How can I get into a bodybuilding supplement commercial?

I'm a teen bodybuilder. I don't consider myself that ripped but people say I am, so I thought would I be able to get into a creating or protein powder commercial or some supplement or workout program for teens. I'm bout 5'8 135 lbs and no more than 8% body fat. I curl 25 lbs each hand and 15 20 lbs with the tricep kickback using flawless form. My max bench press is about 140 lbs.
