Best way to become a commercial helicopter pilot and fund flight training.

Hello everyone, I am interested in becoming a helicopter pilot, specifically in Search and Rescue. I need advice on what options I have. There are not a lot of helicopter flying scholarships, let alone ones for commercial licenses, and I would not pass Military Medical(or have a good chance of getting a waiver). I thought about joining a police department and having them pay for it, but that isn't a guarantee, or getting a private and commercial license in a fixed-wing aircraft, and then getting a helicopter rating, but I would not have a lot of helicopter flying experience to apply for jobs(I think). Does anyone have an ideas or adivce?
