How much should a break job cost? Front only on 2003 Kia Spectra

Front breaks are making noise and most likely will need new rotors or at the least turned. The break light came on about a week ago is this connected with needing break repair?

If the red service brake light comes on, it is usually tied to some other major problem with the braking system. The brake light should not come on just because you need pads. I strongly recommend taking (have it towed) to a shop for diagnosis and repair as it is in an unsafe condition.
