Grace Choi (A metahuman with super-strength and super-human regeneration.) was initially the bouncer for the metahuman nightclub Chaney's in Metropolis until Dick Grayson recruited her for the Justice Lords. Even if she and Dick were old friends, she wasn't very keen on joining until he told her the Lords job would pay her three times more. She has a pay by job contract with the Lords making her pretty much a mercenary. This is a lucrative arrangement since most of the time she is on a job for them in one way or another. The amount of her pay varies from job to job, but in her contract it states "Refusal of a job will result in immediate death." This was a stipulation added by Superman to insure that she never refused a low paying job.
