Chevin Cycles in Otley perhaps? Used to be my LBS up until about 4 years ago. Not the cheapest workshop around but very helpful.
Failing that, +1 for Woodrup. Not sure about Bob Jackson as they seem mainly road-orientated. I've heard good things about both Kendell's in Castleford and Phillipson's in Garforth as far as handbuilt wheels go.
