If it's a civil rights case and there's merit to your claims, you might be able to find public interest lawyers to help out for much less than that. Call around, there are firms in most large cities.
I've contacted one. They said we have a case, but that the federal courts don't really care about rights violations unless there were substantial financial impact. In theory, the DOJ is supposed to investigate our complaint and take injunctive action to correct any agency policy, practice, or pattern that violates the rights of defendants/people. We'll see how that actually works, but I won't hold my breath.
