New car protection detailing in and around Dulwich (SE21)?

[S3inSE21]

I have just ordered a new S3, and politely turned down the dealers very generous offer of a hideously overpriced Autoglym new car protection thing. I still want to get the paint protected, but not as a result of getting ripped off on the price.

Can anyone point me in the direction of a decent detailer in South East London? Preferably SE15, SE21, SE22, or W1J if they are mobile and are happy to come to my office.

Thanks!
