Alas I'm on the wrong side of the pond...

Steamin' Willie is possibly right that many a vocal coach would tend to a classical approach. I favour--and recommend she seek out--a "find your voice" approach. Maybe her voice suits folk or jazz or blues or Lieder but why jump to any conclusion until she's finding her own way through a variety of songs to see how they feel to her. The supportive singaround mentioned by Dennis sure sounds like a great place to jump into the thrill.
