I suppose there are lots of possibilities, but regardless of steering, fees and visits, a non-expert is unlikely to be able to self-diagnose, read a bit of text, and come up with a treatment plan.
The problem isn't information availability, it's experience and interpretation which is not something you can do on an individual basis 'on the side', hence the expertise requirement. If the subject matter at hand was as simple to deal with as "see X, apply Y, get result Z", then that would be great. But as this is not an exact science, such a method does not truly exist, and therefore cannot be made effective in a listicle on a website or other medium.
