I use officiating to pay for college so there is money to be made (even thought you do not need it you will definately make "spending money". I do not solely do it for the money. I do it because 1) I love the sport and 2) I love being around the kids. That being said, I believe that Dan gave you some extremely good advice.
The college there may offer a course like the one here. The course here is called techniques of officiating. You may check into that as well. I would also recommend checking the intramural department. Sometimes they have an officials club where they schedule games for local schools. Last year my intramural dept. scheduled games for over 45 schools. They may not have a club or anything like that but they may be able to point you in the right direction.
One last thing, I found this website. You may find some information on here that will aid in your advancement.
