OK, here's an idea (perhaps a really bad one, but whatever). Do what you normally do, but also add in the following: follow up with the office staff. Give them a free demo. Ask if any of them want to try the software. But don't let them do it live. Take their photo (or whatever you need) and ask them what they'd want done. Then do it at home (even though you could do it live, don't). Follow up in a few days by emailing the before and after images to that office member and CC the doc.

Again, not sure if this would be effective, but office staff, in my experience, would love to talk about this type of stuff.
