I know this is an old post but thought I would comment anyway.

For the past 1.5 years I have been working independently out of a local hospital as a "vendor" one day a week. I was only able to work on hospital employees and I created all my pricing/gift certificate/frequent client/health forms.The hospital did not pay me, each person I worked on had to pay for their own massage.  I contacted the HR department and the hospital had a health/wellness program for employees. And having a massage therapist on call as a "vendor" fit into that health wellness program. The HR department would book me a conference room each tuesday afternoon and they also did most of the  appointment booking. I started out doing solely chair massage but it moved into table massage as well. However, this meant I had to transport my chair and table to the hospital every week. Plus some weeks would be busy and it was well worth my time being at the hospital and other weeks were very slow. Those slow weeks mean no money since the hospital was not directly paying me.

When I first called the hospital they thought I was soliciting my business. Once it was broken down to working solely on employees they were open to the idea of a LMT coming into the hospital.

hope this helps a little.
