how does a felon locate a pro-bono attorney?

I served several years in prison and charged with a felony for missing a 1 court date (which I was not notified about) while on probation. I am required to get a job and attend a class. I have a job that I get paid under the table, and I understand that I might end up going back to prison If I don't get an "official" job. I'm desperate. - Is this your question?
