How would someone go about getting custody of a child back that their parents got custody of after joining military?

I have a friend that joined the military to make a better life for her and her little girl. In doing so, her parents were appointed temporary guardianship of the child. after she went into training she was unable to get in touch with her parents to see about her little girl. They had changed their number and blocked her on facebook and wouldnt respond to any letters. Then she comes home to find out that her parents have started a case to adopt the child without her knowledge or consent. Now that being said, my friend has never been addicted to drugs or in any criminal trouble. We did a petition for her not to lose her baby girl and finally she got a court date and the judge denied her custody. She needs help to get an attorney that will fight for her and not seem like they dont care.
