One thing people tend to forget as it relates to time building for the 1500 hour rule, there just aren't a lot of jobs outside of instructing. As a % of positions I would guess that 80% are CFI jobs.
Banner towing, traffic watching, surveying is another 10%. Part 91/135 gigs that are willing to hire a low time commercial pilot are pretty few and far between.
If you have the money to operate a private jet (owned or chartered) you don't want a 20 year old UND grad meeting you at the FBO. At the charter company I used to work at we jokingly called it "command presence" but more practically it was the "requirement" that any new hires don't routinely get carded when they order a beer and bonus points for at least a slight hint of gray hair.
