I'll go with a definite maybe.
I think Skipper nailed it with the first response to this thread. A lot depends on what is included. Choreography takes time. Are you doing the showcase at a studio event? Somewhere else? Are you the only student dancing the showcase, or willl there be other students to share the teacher's time and help defray the cost? Where will the showcase be held? Etc.
And I know this thread is old, so did you actually end up doing these showcases, ee? If so, do you remember what you paid and how the price was calculated? If you didn't or forgot, no sweat. I'm just curious.
