In search of a lawyer

Hi everyone, I’m a young mom who is in need of a free lawyer. My husband decided he no longer wants to be with me. And since he was providing for us and I was a stay at home mom, I don’t have the funds for a lawyer. If anyone knows of anyone who is willing to help me for free that would be extremely appreciated. I’m hoping to put him on child support, spousal support, and take full custody of my son. As well as change his last name if it’s possible. Thank you in advance
