Offer to have her come stay with you and integrate her into your middle class lifestyle along with.
You aren't going to make enough $$$ with a personal sized op to pay for private school anyway.
And what if she ever found out that you had broken the law to help her? I think she would have a hard time dealing with that.
Your heart is in the right place.
Get her involved with like a softball league on the weekends or something that you can bith do together, that will be a positive experience and let you be a good role model. People are tough creatures. Great leaders, writers, artists, DO come out of poverty and bad home situations... but they need a mentor.
That can be you.
I have always believed that between time and money, what children need the most from you is your time.
