Dont know how much they'd charge you, but last time I asked at The Wheel Specialist at Westerhope, Newcastle they said £40 a rim (16" Turini's). Ive had a few sets done by them before (for a bit cheaper actually!!) and they've always done a great job. Last car I had done there was my Astra Convertable, it was when the snow was really bad, and they did my 17" wheels for £140, but they were really quiet and were desperate for the money.
