E36 M3 Rear Arch Repair Berks - Recommendations?

[MGR]

Looking for somewhere either near Reading, Berks or Telford, Shropshire.

This must be a pretty common repair given the age of these cars now, I was hoping there would be a few bodyshops that are known for work like this.....?

I need the car for work so I really need somewhere local.

Thanks in advance.
