How to become a college football official

[Mia6798]

I have been a High School Official for the past ten years and I want to move to the next level. How do I get the information to apply and join assn's at the college level. I have made some contacts but for some reason they are have not helped. I have worked spring practice for a local college and felt very good about the job I did. I know I can excel at being a college official. but My window is getting small. I am 44 yrs old this month and understand that it's a young mans game. What should I do?
