COMMUNICATE WITH CLIENTS ONLY VIA EMAIL:
be brief in your request for sessions and understand that I am
usually fully scheduled from two- to three-weeks-out.
require payment via PayPal up-front before scheduling a session.
I have received notice from PayPal that you have sent your payment,
I will email you with your session date.
every session I also need a client's complete street address.
This is how I will "identify" the person at the beginning
of her/his session.
