Help with Legal Assistance for Sacha

After 17 years my sister has gathered the strength to leave an abusive marriage. Due to threats of physical violence she and her two children are currently living in a secret location, and she has filed for divorce and a restraining order. Just today Sacha had to face him in a hearing. He was in attendance with an attorney, however she is currently unable to afford one. On top of assistance with the restraining order and divorce, my sister also must pay for a Guardian Ad Litum for her daughter, as she was in the process of making her permanent guardianship into a legal adoption. Sacha has already won, simply by gaining the courage to leave, but now she is in desperate need of assistance to ensure she and her children are safe, and able to remain together. She has consulted with a family attorney, and was quoted a range of 9K to 14K depending on how many hearings they must have. This is why I am setting a goal of 15K. Anything you can give is so greatly appreciated. Thank you in advance for your kindness.
