From experience, the grating sound is the starter not disengaging immediately after start, usually worn bushings or springs within the starter cause this since the starter doesnt back off the ring gear on starting.
If the grating sound is before the engine starts, then the internal bearings on the starter are likely bad
In terms of fixing, any electrician worth their weight should be able to strip and rebuild a starter.
