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 wheel-chairs to those trying to get into medical billing... Your insights would be helpful. Thanks
