Are there any family law attorneys that take payments, or it this a myth?

I need a family law attorney for an upcoming custody case. I have contacted legal aide, and various other avenues re: reduced rates but no one will take my case due to there being no direct family violence against me from my ex recently (there was while we were married). We are divorced, he gained temp custody of my 7 year old son last year due to a material change in circumstances on my part (i kept all parental rights). He has since gone back to jail for Domestic Violence, the judge awarded custody to the step mom for 2 weeks. I had that reversed and temp custody came to me. Now we have to have a new trial to decide final custody.I need an atrorney that will take payments and who isn't afraid to go up against Butts County's good ole boy system. I am finding this to be hard to find......
