Finding a skilled, trustworthy lawyer who will fight on your side is extremely rare. Still, one option you might want to try is get in touch with the prosecution team in Georgia that went after that other cult that abused children. It was reported on Rick Ross' site, but I can't remember the name or the details. Perhaps another poster can remember.
This is the page that lists profiles of cultic studies journal (csj.org) individuals. Try contacting some of the lawyers here. The CSJ website can be tedious. Be patient.
