My clutch seems to be "bottomed" out

My clutch seems to be "bottomed" out. It got so bad that I would have to start the car in second and just go, couldn't come to a complete stop or it would stall. I have had it adjusted or lifted twice but it only lasted a week or so each time so I parked it. My daughter just got her license but I don't want her driving a unsafe vehicle. Can you tell me if I need to just replace cable or what? Can you tell me approx labor cost to expect? Being a single parent any money I can save helps a ton! Thanks for any advice you can provide
