I think you can pursue that – you volunteer to help out with production at your local BY, try to get on board some of these women’s movies that they produce from time to time. Maybe you can even get a position! But I’m not totally sure it’s a good idea for a long-term goal – there just aren’t enough venues in performing for a frum girl to pursue.
There’s also nothing wrong with trying to balance your hobby with another job. You can go to school and get a job as whatever and still pursue your dreams.
