what type of lawyer do I need to sue school district?

I have a daughter who is now 17 years of age. I had gotten custody of her by paying her mother a cash payment instead of sending it to her through AG's office. I knew it would be considered a gift but i just wanted my daughter, her mother is a drug addict and dancer/stripier/alleged hooker. I got the child back and heard the most horrible stories that my child went through. I called cps and made a report and contacted local police and filed a report for child abuse. I was told by AG's office to file a affidavit of possession and had it notarized and gave to AG's office. I also went step further to protect my self and file a SACPR (suit affecting child parent relationship) and had the mother served by local constables. She was served and paper was filed. fast forward to three months ago. I had enrolled my child a local public school and I went to pick her up one day and I waited and waited and she never came outside. I went into the school and she was no where to be found. I immediately call the police and they instructed me to go to police station because I was very upset. I went down there and during the interview the mother finally called me back and i told her i was at police station because i could not find our daughter. She informed me that she had child and she was not returning her. I let her talk to police and they said since mother had her it was a "civil matter" and I would have to take it up in civil court. Well i went back up to the school and they told me the mother showed up with extremely old papers and said she had custody and they let her withdraw her out of school, and leave without even a phone call to me after I had made it very clear NO ONE was supposed to have access to my daughter that was not on her info card on file at the school. I finally got my daughter back and now she is no longer in school and pregnant. I also found out that on the day that she went missing that the students in transition counselor was hiding clothes in her office for my daughter, and on the day she left the counselor took child in the morning to another town in her own personal car with out my knowledge or consent to pick up mother and bring her back to the school and have her withdraw her, and not once did anyone ever call me. Well after being with her drug addicted mother for no more than two weeks the mother went onn binge and threw my daughter out and my other daughter located her living on streets, now she is safe with me but she is pregnant and I feel that if the teachers and counselors had done there jobs and followed there own rules and protocols that she would still be a high school student and not pregnant, because when she was with me I made sure she had birth control and stable environment to live in. Now thanks to there actions and lack of action her life is forever changed. I want to know if I have any rights or can they just do what they feel like? I got really sick after daughter left and was in hospital for one week. Any help would be great. I am not trying to get rich, i just feel like they acted unjustly.
