Erin and Steve, thanks for the replies.
I can appreciate the pitfalls of personal referrals, especially when intuitive readings aren't as cut and dried as, say, Steve's recommended PhotoReading program.
I'd been thinking along the lines of how you can set up a doctor's appointment with a nurse practitioner instead of the head physician of the practice, but now I doubt that's an applicable comparison.
Still, we can look on the bright side: all these high-paying customers are subsidizing great free content for the rest of us!
