I have my website and a monthly newsletter. And some business cards too. And of course word of mouth...Works for me.
I also have a digital camera and a special e-mail that lets me create my own stationeries. PM me if you want more info on that as I don't want to be accused of advertising here for them.
When I pull the cards, I photograph them, then put them into the computer, photo edit them and then make a stationary with the photos. To me I personally would want to see the cards that came up in a reading for me, so I always send them to the querent so they too can see them.
Of course I have PayPal on my web site. So people pay me before I do the reading. After that is done it takes them to a page where they write me and send me the question. I get both notes at the same time (the PayPal one and their note) and then I write them back, refine the question as needed, do the reading and e-mail it back.
