Jewlwery - Im pretty sure that you come up with a concept and take it to a jewler, they should know what to do next!
Stationary Etc - You can make a design based on your ritual or whatever and then get things made at Staples or another kind of store. You can also print things on your computer.
Website: If you would want a website - PLEASE go to my boyfriend's site -
CMDesign He does websites and logo creation (maybe he can help with that too). He can suggest a really good host (the thing that will give you the .org domain!) He did my chapter's website and is maybe going to do other Phi Sig sites. If you want to contact him, please contact me too and let me know the kinds of things you want. He doesnt fully understand greek life (hes getting there) and he may need me to explain things.
I hope I helped!
