I'd suggest dropping the requirement for payment info in order to start the free trial. I was going to try it out on my calendar - with a colleague in mind. I don't schedule enough appointments to make it worth it to me, and I'm not really interested in giving you my CC details just to test it for someone else. At the very least, you should make the demo link easier to find.
