Anyone Into "Medical Billing" Niche?

My wife has 25yrs experiance in this field, and I think she could provide
info of value, and provide Q/A to website visitors...

However, amazon products seem to be "low value"...

Are there any sub-niches for "Medical Billing" that could
also appeal to those that are looking for "medical billing"

If you run such a site, then maybe you can tell me if this
is a decent niche to get into. Health Care is a big business...
Unfortunealy, medical billing courses is different then trying
to offer...
