i can give you url of the best attorney resource iv ever come across, it has helped me and my friend both...not only it has all the top lawyers mentioned of each state and city but also it covers legal and emotional aspects related to divorce ...best of luk :)
pro se attorneys only work on matters of enormous importance. Primarily things with the death penalty, the environment and the like. There are no pro bono family law attorneys.
With that being said, there are still attorneys that may be able to help you, depending on specifically what your problem is. Many Legal Assistance offices provide assistance or your state may have a volunteer lawyer referral system. If there has been previous abuse in a marriage say, and there are minor children, the domestic abuse shelters can help you with obtaining custody and child support.
It's hard to know where to direct you without knowing what help you need, but start with those.
