when people ask I always point them to Miracles. they do custom work, have been around for a while with a great reputation, and the prices are very reasonable. I don't know anyone local who does glass work.
if you want something local in acrylic, Reef Culture has an acrylic guy, there is Ceaser, & there is TruVu in chandler.
EDIT: also, come over this week and help me re-arrange my tank for this nem. Good time to do it with the fish in hospital tank.
