Depends on what needs to be done and how good you want it.
If it's just a 'lacquer overspray' then $40 - $80 should cover it. If you're stripping off the old finish and doing something special (eg a 3-colour sunburst, or a metal-flake custom job etc) then you can expect triple that (or more).
If it's a really high-end job you're looking for, call Scott Lentz in San Marcos CA. He's expensive, but it will be perfect.
