I've had many people write to me, and ask about my business, asking for advice. My suggestions are if you are going to do online readings, spend a lot of time seeing if you actually CAN do readings in that fashion. Tarot readings for parties or events can be very lucrative. Or, our local mall rents kiosk space by the weekend. Tarot Business could be quite brisk on a Saturday or Sunday.
Various readers form a kind of union, and then appear en masse on certain nights.
The readers do quite well and even develop their own following. I submit to search engines and other sites with regularity. I have a list of information, such as addresses, keywords, and site descriptions, that I save on file. Then I can easily cut and paste the info when I'm on a submitting binge. I have a large mailing list.
