Your next steps after primary training for the Private Pilot certificate, no matter what might come later, would be instrument rating and commercial certificate, of which, the comm requires 250 hours total. The most "common" path is to get your CFI right after that, and build hours as a flight instructor. Pay may not be great, but at least someone else is paying for the aircraft. It's kind of a goofy system, where the youngest, newest "professional pilots" are the instructors, but the way the regs are written, that's really the first thing you can do to get paid for flying. There are a few other gigs, as mentioned, skydiver hauling, survey, banner-tow, but none as prevalent as the instructor route.
Job opportunities for very low-time pilots are rather limited. Even the small freight companies must operate under Part 135, and the minimums by FAR are 1200 hours for PIC (with IFR capability). 500 hours minimum for a VFR-only pilot under Part 135, an extremely limited category, maybe only in use by sightseeing operators such as Grand Canyon tours or such.
