FGG,
You may want to check with your city/county social services. Some states provide free legal fees to those on tight incomes, and at the very least, should be able to recommend a good attorney. Just a thought.

My heart goes out to you. I would have sold the shirt off my back to pay for attorney fees to keep primary placement of my son and it worked. Don't forget to pray - God answers in mysterious ways sometimes, but he always answers. I'll be praying for you and keep us posted.
