Alloy refurb basics?

[Minstadave]

Having threaded my locking wheel nut and scratched the chipped and scratched my wheel in the ensuing battle I need to refurb an alloy. I've managed 3 or 4 chips through what looks like lacquer and metallic paint. Nothing deeper than that.

Could anyone tell me how much a repaint will cost and how long it takes?

Can you just get a single wheel done or will it not match the rest?

Thanks for the help.

It's a standard Audi A3 sport 17" wheel, nothing fancy.
