Some might want to work directly with loved ones assisting them with the process of death, preparation of the body and memorials. If this is you, you might be interested in becoming a death doula. It this speaks to you, contact the National Home Funeral Alliance. The internet offers many options for training, but the national office would best direct anyone interested in beginning this work.
Perhaps these two options do not fit what you might feel you want to do. Perhaps you belong to a religious or spiritual community and your traditions fall outside what the conventional death care industry likes to do. For me as an Orthodox Christian living in Illinois where my loved ones must hire a funeral director, I know that having a traditional funeral will be difficult but not impossible. I suggest if you belong to a spiritual community, perhaps you can begin a ministry or task force to help those at the time of death and following. If you are the leader of such a community, I highly suggest you begin looking for people within the community who can do this work.
People every day face the death care industry and have to navigate a way through all the roadblocks set up by the sales people within the industry. Maybe you are not one who can take a step outside the norm and help change the face of death care. Maybe you are. Maybe you have thought about doing something to help change death care in our society. If you are, make a plan and then take small steps forward. You might find that this is the work that fills your heart.
