Please Help Me Keep Joint Custody Of My Kids

I've been in an ongoing custody battle for 4 of my kids for the last 3 years. This is a case of parental alienation and I can't get anyone else to see the evidence I have and fight for me. I recently discovered my attorney, who my family and I have paid over $15,000 to in the last year alone, wasn't really fighting for me or my kids, she was just continuing the case as long as possible to run up the bill. We're out of money to fight and my ex wife's family are millionaires with unlimited funds to keep me from my kids. If I ever want to see my kids again I need a new attorney who will actually care about me being daddy to my kids. Please help if you can.
