I was visiting with a Florida provider
and she mentioned a marketing strategy she
uses.  Perhaps TC providers might want to try it.

Our enterprising Floridian advertises a special
where the 16 or 17th person to e-mail her gets a
free appointment.  The non-winners get a $25 discount,
as a consolation prize.

Of course, someone using this strategy would have
to have an impeccable reputation (otherwise hobbyists
would suspect that no one really wins the free date),
and at least some of the winners would have to verify
that they won on the board.
