But yeah, if you're just getting the spokes replaced, it should be somewhere around an hour or ninety minutes worth of your local wrench's time, so multiply that by whatever $/hr your guy charges. If they do it flat rate, I'd guess around $50-$75 -- but this varies widely, even shop to shop in the same town. Especially if you've done a lot of business with them in the past.
