What do you want done? Body resto? Interior? Engine?
Don;t limit yourself to someone near by. Decide what you want, what your budget it and then start looking for referrences on here and other foruns to see who people recommend.
My bus is with midland paintwerks at the moment for a body resotration and bare metal respray. They are not the cheapest but they are, in my opinion, the best.
Yo will get what you pay for. A £1000 blow over will not look like or last like a £4000 bare metal respray.
You also need to budget for the hidden issues that will be uncovered, mine look pretty solid and straight but as the paint came off it was apperent it had been repaired badly after a heavey accident. Add quite a lot to the costs of restoration.
