Any money in motorsport events?

I used to race ATV's in a regional cross-country series based in NC and SC. It wasn't long into my racing that I bought a GoPro 960 and began making videos from most of my races. Fast forward to today, I am no longer racing but I am still doing video for some of friends and I want to get nto it more. I would love to start a small side business ilming different motorsporig events ike race, FMX shows, car drag racing, driting, whatever has wheels and a motor. Is there any demand for this right now, anyone know?
