Has CPS filed a lawsuit yet? If yes, the court should appoint an attorney to represent her if she asks. Have you had any hearings yet? If not, at the first hearing she can ask the court to appoint an attorney. If you are already past the show cause hearing or the adversary hearing (which are the first two hearings that are held in these kind of cases) then she can file a motion that just asks for a court appointed attorney, get the court coordinator to set it for a hearing date and send copies of the hearing with a notice of the date of the hearing to CPS and all parties or thier attorneys . Then, at the hearing she should just tell the court she cant afford an attorney and ask for one to be appointed.
alternatively, she can try to hire an attorney to just draft the motion for her (in her own name) and tell her how to get it filed and set for hearing.
In any case she DEFINATELY needs an attorney.
