Permaculture consultant. I've met people who are going down this route. You can subspecialize into agriculture, permaculture for fire protection, anti-drought structures, pollution protection for sensitive habitats, pollution protection for schools/care centers/hospitals, etc.
There are permaculture schools across the US, Europe, LatAm, etc. Credentialists will be looking for a degree in geology, soil science, agriculture. You don't need a Bachelor's, an Associate's with a high GPA and strong letters of recommendation is enough - go to community college.
Personal trainer / nutritionist - applied bioenergetics and endless in subspecialty.
Doctor - expensive and time consuming but grants high credentialing, opportunity for private practice and actually helping patients.
Personal chef - another job where minimal credentials and good marketing can meet bioenergetics in a low overhead, high profit margin way.
Peat released a newsletter than people could subscribe to for cheap. Bioenergetic/Peaty living means ending up in a sole proprietorship and releasing your own content of some sort.
Regardless of your product or service, you need to be in a position to set your prices, manage your costs, and control your tax situation through deductions, credits, etc. Working for someone else on a salary or wage basis is not Peaty.
