just go round some local bodyshops, ask to see some of the work/paintwork theyve done and if its good enough for you get a quote, then goto another bodyshop, tell them the last quote you had. people have different experiences with bodyshops, best to just go and have a look.
and price never determines a good job. you can pay 2k and get a s**t respray, at my last place wede do resprays for 600-800 quid and they had to be perfect.
