Medical office - Don't know where to start

I am building a medical facility on paper that I would like to make a reality. Right now I have a small outpatient clinic that I rent, but I would like to turn it into something much bigger. I am hoping to find the right forum(s) of peers and mentors, specifically in the following areas;

- Buying a commercial building

- Funding the start up costs of a medical office (imaging suite, laboratory, therapy equipment, office furniture and supplies, etc.)

- Tax planning for start-up and profitable years.

- Legal nuances of an assisted living facility and health care in general
