The Independence Institute’s Future Leaders Program. As a law student, you would work directly for me or for Rob Natelson (retired U. Montana constitutional law professor, and perhaps the most knowledgeable person in the world about American legal thought and practice in the Founding Era).
The Independence Institute is a think tank, not a public interest law firm. However, we do sometimes get involved in important constitutional cases, and my recent interns have worked on cases such as McDonald v. Chicago. We are involved in the constitutional challenges to ObamaCare, and plan to stay involved all the way to the Supreme Court. That said, your work at Independence Institute would probably involve more time helping with Issue Papers, op-eds, law review articles, and other publications than it would with brief-writing.
