How to get started in officiating HS Football?

[dinoian]

I've been officiating a bunch of sports including flag football at the Intramural level for about 5 years now, and I'd like to move to a higher level (and the pay has to be better than $10 an hour). So how would I get into officiating middle school/high school football this upcoming fall? I'm currently living in North Carolina; are there any state organizations that I should contact for more information? I saw that there are annually meeting sessions, but what should I do to prepare for them? Any suggestions on how to make the transition from flag to tackle? Thanks in advance for all your advice.
