Try Will at TGM Motorsport in Fleet, just had my R33 done there - handy for me, 30 mins drive. Or if you don't mind a trip up to Wembley way RT Performance do repairs and spray work.
Cost wise, no idea really, looking at cracks etc though and having a very wild punt, £200-300 a panel to a very good standard? I had my front bumper on the Zed just resprayed (so no repair) some time ago for around I think £250, that was a few years back.
