Help Jessica Fight for Custody of Her Son

Hey everyone, my name is Jessica, and I'm raising money to get a lawyer to fight for custody of my 2-year-old son. My fiancé left me in September after being a stay-at-home mom for the last 3 years. He's attempting to take full primary custody of our son. He left me with no vehicle or money. He took our son, most of his stuff, and hid for a month with no communication. He wouldn't even come to church. Eventually, he let me see him, and I wound up getting my son. I've been searching for a job, but with a 3-year gap in my work history, it's going slow. I'm terrified of losing my son. I've talked to many lawyers and the best price and lawyer I could find wants 2000 up front and another 2000 grand within 30 days. Any help will be greatly appreciated. Thank you.
