When I was doing corporate flying I was contracting flight attendants for $400/day plus expenses. Then I spent a lot of money cleaning up their mess and went on to find another company or flight attendant to hire. Found a few to rotate between depending on availability.

I never could get a contract pilot, the owner scoffed at paying $1000/day + expenses. So he just wouldn't fly or accept the charter trip if we had pilot issues.

FWIW.
