I don't know the bike shops in Austin, but it seems like a city that would have at least one bike shop that employs a good wheelbuilder. Before I started building my own wheels, I generally got wheels from an LBS in Seattle.
If there is a bike co-op or something like that in your area, you might become a member; that is what I do; it saves me a lot of money on tools, and it put me in contact with other DIY-type mechanics who can give useful advice.
