I know someone who doesn't know how to play guitar but has a basic acoustic guitar and bought strings but it needs stringing, do they charge to string a guitar and if so how much?

They did a pretty extensive rebuild and cleanup on my electric and it was almost ridiculously low priced. . .I can't imagine it would be much at all to have one restrung.

I'm pretty sure they do basic guitar work at Mark's. I don't know how much though. I'd call them to get specifics. If they don't do stringing, I know Northern Kingdom does.
