Interested in Refing

[mfs914]

i am interested in becoming a football official for HS football. I currently umpire baseball, and have done that for over 5 years now. My question is i never played organized football, and really the only rule knowledge i have is from watching it on t.v., do you think it would be difficult for me to start officiating a sport that i have never played before. I love to watch football i watch a couple of games a week.
My other question is how much of an investment would it be. I would guess that it is less then my baseball gear.

Thank you and if there is anything else you think i need to know i would really appreciate it.

Thanks
Mike
