How can I get custody of my grand kids in foster care in Florida?

I live in Alabama and they are in Florida my daughter and her boyfriend whom has been arrested many times for drugs and robbery was just released from jail .Both stated they wanted me to get the girls out of foster care so I put in for an ICPC but now he is trying to keep me from getting them. He and his mother are trying to get them she has a long arrest list also. The caseworker won’t even try to work with me on visitations or anything and I am tired of it all not getting anywhere. Everyone said if I had a lawyer this wouldn’t happen. The baby was taken at 2 months she is almost 1 year old I have seen her 3 times I have begged to see her over and over her birthday is soon I get no reply from anyone. I have no money, nobody care about these kids, really, no one will help me. I have made them a bedroom and done all they have asked me to do got a background check and everything, filed out tons of paperwork also. Please help me move it along before he gets them and ruins their little lives.
