Custody of my daughter from sick ex

Almost 2 years ago my husband and I had our only daughter together. Even though our marriage was far from perfect I always tried to make our relationship work out for our daughter. I had forgiven him being physically and mentally abusive. I had forgiven him when he had quit his job when our daughter was a newborn and was forced to start working a couple weeks after giving birth. I had forgiven him for putting his wants before his family's needs. I supported him in everything he had done. Even if that meant working harder at my job or longer hours. Eventually I realized that I wanted more for my daughter and myself. The dysfunctional household that we were living in with my husband was starting to take a toll on both my daughter and I. I packed our stuff and left to go live with my grandma, who I knew was going to do everything in her power to make sure that we were happy and taken care of. She watches my daughter while I work full time. To pay for my car (I don't own yet) and child expenses. I haven't received any help from my daughters father as I had filed a restraining order on him for stalking me to my work and attacking me when I got out of work. But he hit me with a divorce about 2 weeks ago. And now the court wants to consolidate the order of protection and divorce together. His parents are funding the money for this lawyer and divorce. But I on the other hand am barely making it by. Looking at the retainer alone in order to get a lawyer is mind blowing. I feel like I'm backed into a wall. There is no way I can afford a lawyer. I'm asking for is the retainer of $1,500 for the cheapest lawyer I can find. I know it's a lot but anything helps. I don't want to lose my daughter because I couldn't afford a lawyer. She is my everything. Thank you.
