Hi Tracey,
I agree with Peter about taking her to a local astro club event.
She will get to look through lots of different telescopes and you will be able to ask questions and get an idea of what you can see through different scopes.
My local astro club (in Melbourne) has a kids section which meets once a month on a Friday night, so hopefully there will be something similar close to you.
Oh, and they also may have scopes available for loan, as my local one has.
