I bring in 5-7k a year DJing and personal training. They're technically "work" but I'm literally getting paid to live out my hobbies I already do for myself, which to me is passive income. I would, however, like to turn a programming side project into something that's passive income.
I shoot hookers for money, photographically. The kind of mid/high-end ladies that have their own sites and galleries.
They're a hard market to get into, but frequently one girl will know another five or ten, and personal recommendations go a long way.
Those girls, and retired people who want pictures of their cats/dogs are the only consistent group of people who seem willing to pay for portraits/photographs.
