if youre looking to have a rim drilled and stainless spokes, there is pretty much one place that does this. buchanons. i can onlt tell you that they do ok work, if youre not looking for some out of the ordinary pitch, other than that they are a total pain in the ass to deal with. and anyplace you get parts from most likely buy from them. there are places in england that can give you a good deal on parts and sell you the new akront. there are a million different places that can build you a wheel though. aaron is one guy to talk to. although hes got plenty on his plate now. that and i dont know how much he charges. where on the east coast do you live?? i think most listers are in new england and they can point you to a decent place. if further south, i can help you out proabbly.
alot of people will tewll you to do it yourself and if you were lacing bicycle wheels, thats harder to do. i trust it to other people who know what they are doing.
good luck
