Like many careers, musicians life differ hugely, some international stars, some prefessors in music college, adjudicators,some teach in private schools, board examiners, some struggle to find a pupil, some do local music service, teach year 2 group recorder. But if you absolutely love it and really talented and willing to work hard, I am sure you will find you comfortable place ,the life style you love. Some people enjoy evening performance, as the centre of stage, some don't, would rather sit down as audience, but a music lover.
The music teachers I know, both long time examiners, one is orchestra conductor as well, both teach in private schools, and teach privately. Both have long enough list of pupil, and long list of pupils's name on tropies, both have wonderful reputation made me proud just by knowing them, have such good energy for their age and love of their family life . Both have definitely a high above average income, of course they are working hard you know.
How old is your DD, when did she start, how much practice did she do to achieve where she is now?
My another comment is :when you are not sure , you are not ready. If she is absolutely telented, with little teaching, fraction of practice time, achieved far far beyond her age, full of natural sparks, natural style, then you will know what's next.
