Audi A6 - Best place to repair scratched Audi in SE London - pitstop

My Audi A6 has been scratched in 3 places on the back corner of my bumper by some kind soul (!). The scratches have taken the paint off but are not that deep but more than a scuff. I'd be grateful if anyone can recommend a good, honest repairshop in South East London or nearby and roughly how much it may cost - ballpark (I appreciate it's hard to say without looking at it).

If it's a bumper corner it won't be that noticeable. I would buy a colour match scratch repair kit from Halfords for £12.95 and build up the scratch with paint, laquer. It won't be 100% perfect but only you will know it's been repaired.

Thanks - I think I'd rather get it done by a SMART repairer though as the car is on loan to me and I feel terrible - even though it was not my fault. If anyone has any recommendations in South London, if not South East London, please shout.
