Can anyone recommend a decent bodyshop in SE Essex?

[BigNige]

My X308 has the teeniest paint bubble at the base of the rear screen and I want to catch it before it goes too far.
I appreciate that the whole valance across the car will probably need to be painted to make it match properly (or will it?)

So I'm looking for recommendations of bodyshops in SE Essex that will do a good job and not fleece me for a bunch of overspray and paint spatters on the window.

cheers
