legal aid

I once asked helped for my custody case here. Now I need more help.

I was trying to find legal aid-free legal service but I was told that they have no resources to help me. I don't know the free legal service system and my case is complicate. However, I am in very tight budget as I have no income now. Anyone know how to get free legal aid? Or anyone know how to borrow low interest money to pay the lawyer? I guess I need $10,000 lawyer fee. I am urgently need to file the custody case.

Thank you
