Replying to Film Career Oppurtunities

I know guys like Nick Martini and Eheath film the news,weddings, commercials and other stuff outside of skiing to help improve their filming and make bank doing what they love.

What are ways that you guy's on NS make money from filming and how would you recommend getting into the film industry? I was thinking of starting to do real estate but would love any other suggestions or cautions or anything else that could help me out.

Thanks.
