Start with the Goetia and the Golden Dawn (Hermetics/Thelema). I believe Crowley actually did one with that particular demon, and its on the internet. I came across it on google recently while looking for a different sigil. You don't want to "in"voke, you want to "e"voke. Invocation is calling INTO you. Evocation is calling TO you. Big difference!
