St. Louis teachers for emerging professional?

I may be in St. Louis for a year (starting September) for DH's job. I'd like to have a teacher and at least one good coach there even though I plan to fly back home once or twice for lessons. I won't be affiliated with any of the schools in the area. Are there good teachers and coaches available to non-students? I'm an emerging professional soprano specializing in Wagner and Strauss.

Thanks in advance to all who reply!
