Worth traveling to someone who sees it as a hobby. The cost will be lower and you can receive what you need, rather than everything. Presuming machine polishing is really the only bit you can't do?
^ I would be willing to do it, but not until after the winter. (I have 3 cars, plus my own, waiting to be done once the cold and poor weather has gone LOL)
Im based in Nottingham and as JD said, would be a lot cheaper. If you want a professional, I can definitely recommend JimWD (White Details).
