I really respect why you donot wish to charge people when you are helping them/ offering healing. I don't think you should do option 1, cos life is too short, I say do option 2 and ask for donation, or only charge what people can afford to pay, as some people do have more money than others. Come to agreement with the people you work with, give yourself a time frame and see how it goes.
You'll be surprised what will come your way.
I hope this helps x
