As a recently graduated member of the ASWSUV student government, I can help you out with information if you need some Infidel. I also started a game design club and got funding for it, so know about that process. Although Michelle or Rachel would also be happy to help you as well(OSI Manager and OSI office coordinator). Basically you get $200 for the year as a registered club, and can request further funds if you like from the senate (but you need to show how it will benefit the student body to spend it).
This is the RSO registration form:

Sample RSO constitution (you need to change it to fit your club's rules):

You will also need a faculty or staff member to act as your club advisor. It is true that non students can be in the club, however they cannot be voting members of the club, for that you have to be registered as a student.
