Doing the business

I've just sold a sigil on ebay. Sigil Magick is most often associated with A.O. Spare and latter day chaos practitioners and is a simple, but effective method of achieving magical success. Given that this sale goes well, I'm tempted to set up a site on my domain occultica.co.uk, and sell more. The premiss is simple, people send me their statement of intent (the outcome they want to achieve from firing the sigil) and I create an appropriate sigil for them to fire. I think sigils created in this way have a better chance of success since the person firing the sigil has no idea how it was made and thus no attachment to the process, which is essential if the conscious mind is to be bypassed properly. I know a great many of you will think I'm a loony, but those who don't, suggestions, comments?
