Ms. Carrie - welcome to the site. Don't let these strange people scare you away...
Now that you have your license, the next thing you might want to do is find a local official's association. Contact your state association office for information on local associations. Then contact one of the local associations for meetings, gatherings, clinics, etc. They are usually the best source for how to get started, and who to contact for games, whether it's an assignor or if you need to contact the school AD directly.
Each area is different, even withing the same state, so it's hard to give you specific advice without knowing exactly where you are located. But it never hurts to start asking questions, and the best place to start is your state office where you registered for your license.
Good luck, and keep checking back here for advice. Lord knows there's plenty of people here willing to give it...
