I know of a few. Are you wanting to get involved in the detail itself or just want someone to do the job for you whilst you are at work?
Also what are you looking for? Do you need paint correction? Again budget comes into this but I suppose you can discuss this with your detailer.""
Ones that I recommend and have used in the past are:
Graham from

Dave/Gordon who can be contacted via email or phone at
