Try just dents. (paul walker) is at darlington and is a perfectionist. They travel about but not sure how far they go. Look them up as ive not got the number but i think you will be very happy with the service.
i used a company called dentking, came to my work in gateshead and took a dent out my civic, amazing to watch and charged 60 quid. Dent gone completely despite several bodyshops giving quotes of several hundred quid and saying it would need painting etc etc.
