Does anyone know a disability-rights advocate willing to help for free? Randall, Los Angeles

I'm facing a visa refusal appeal, with a hearing on November. I earn too much to qualify for legal aid on paper, but not nearly enough to pay a lawyer's retainer. I'm looking for a qualified disability-rights advocate licensed in California who might be able to review my documents, prepare me for the hearing, or take the case pro bono or on a reduced fee. I've organized my documents chronologically, and I'll share them with the lawyer who agrees to help. I can travel to your office in Los Angeles or meet online. I understand that the time of a lawyer is valuable, and I'm deeply grateful for any help or for suggestions of organizations that could assist. Thanks for being kind about this.
