I know it's been a while since you posted about starting a club, but I thought I'd post here in case others were thinking about starting an amateur radio club. What I would suggest is that you contact the Affiliated Club Coordinator for the section that you're in. You can find a list of sections by going to http://www.arrl.org/sections
Click on the appropriate section from the list to go to that section's webpage and then look for the Affiliated Club Coordinator in the right-hand column.
