Peter has a great site and guarantees any wheels he builds. There is a link on the home page for "wheelbuilding" in the text. Lot's of interesting reading here.

Also, Sheldon Brown will build wheels for you.

There is also some guy in Texas, but I can't remember who he is. Maybe someone else knows him.

I'm sure these folks will tailor wheels for you to suit physique, riding style, etc, etc.
