I don't know of any in your area but I can recomend "designer browbands". They made a beautiful tweed jacket for my (grown up ) daughter. They were very helpful and this was all done through the post with accurate measurements and photos.
Other option is to go to HOYS or Olympia and get it done there. AJ, Mrs C and DB all make top quality jackets which are worn in the ring at HOYS - they will send you swatches of materials and you can give them the measurements for them to make the jacket for you.
