attorney medical malpractice

I am wondering where i can get answers to how to file a medical malpractice lawsuit without an attorney?
Our son was killed in a hospital and unfortunately those responsible are getting away with it. Really need to find help in filing first documents to get ball rolling. Don’t want any money but we must get some kind of justice for our darling boy and we feel we must bring this hospitals screwups into the light of day to protect current and future patients. And yes i have proof just can’t get any lawyer interested not enough possible cash in it for them. Just need pointed in right direction and access to legal documents and filing fees.
