"I'm already 40+, and it looks like my company doesn't go away in a few years and we are so short-handed" FANG employee for over a decade quit her job, opened a consultancy, and sold back what she was doing to former clients of her company(and their clients). She sold back what she was having to do to make up for this short-handedness, and the incompetence of many of her former colleagues.

She did it at 3-400 times the markup she was being paid while employed :) because they were time critical.
