Similarly, I know carpenters and plumbers who will get the job done - and make a lot more than the aforementioned lawyers. These pros can demand hourly rates of anywhere from $60-$80, but more often will make $250-$500/hr by quoting a job price and doing it quickly. And it's no problem for them to drive to all their appointments in their 1997 Ford E series wearing flannel and jeans.
I could also introduce you to janitors that make six figures a year because they know how to penetrate insurance bureaucracies and get black mold cleanup jobs.
If money is your aim, pick a job out of a hat and be excellent at it - and not just the actual execution, but the promotion, estimation, and pricing of your talent too. If you can get into the 25th percentile of solving problems in your expertise, you'll be well compensated for it no matter what it is.
