Step one is to find a Schutzhund club near by that has a training schedule that works with your schedule.
Step two is to get your dog tested and see if she has the nerve/drive for the sport.
Step three is to listen to your TD and helper, do what they tell you, and learn.
Sending your dog away won't teach you anything about the sport or how to train for it. It won't teach you anything about your dog, it won't teach you anything about looking for a good Schutzhund prospect. It will also probably cost you an arm and a leg and you'll be able to tell your friends and family your dog has a title that neither you nor them know what it means.
