Help me afford a lawyer

I have 2 children, I am a solo parent to them, their father has been around intermittently for nearly 2 years. He sees them occasionally, he suddenly wants more access to them and is not going about it in a very positive way,....needless to say his financial situation is much more robust than ours. I work also, Its all very hard work and no matter how hard I work I am not really getting ahead, creating a stable home for my children is my top priority but having bought him out of the house to do this, the mortgage is killing me. Out of desperation I have contracted a lawyer and want to do the best I can to ensure my children have a stable environment and home, there has been a lot of upheaval, stress and damage done already, Please help me to afford the counsel I need to protect us.

I am happy to discuss in more detail if you would like.
