I agree with Gokul, that you can find college or graduate students (depending on the level your daughter is at) who can tutor. If she's in secondary school, sometimes the teachers know who is available as a good tutor. In colleges, there is usually some sort of learning resource center on campus that can refer students to tutors, and sometimes can even find some limited free tutoring from students paid to hold office hours at the center (that's really variable from school to school). Some tutors also just advertise their services in newspapers or on bulletin boards in places like laundromats near campus. Just like anything else, ask for references if you hire someone that way, and if it's their first time tutoring, perhaps you can arrange one free or half-price session to see if they're any good before scheduling regular full-price sessions.
I wouldn't recommend the big "companies" for tutoring. They have a more rigid, one-size-fits-all approach, and I don't think that's what most students need when they need tutoring.
