Again, the details matter. If you're calling new attorneys, are they asking if you're currently being represented? They won't want to split the fee, and will turn you down just for that.

If you're calling asking if they'll represent you in Federal Court, when you really need representation at the appeal level, you might get a different answer.

You seem to really need somone that will advocate on your behalf. Is there a relative or friend that would be willing? If not, you might be able to find someone in your community. Social Services can likely give you a referral.

IF, you are at the appeal level, someone else can write it for you, it doesn't have to be an attorney. When you get to the Federal Court level, it has to be done pro se or by an attorney.
