Are there any 7 on 7 leagues in Kansas City for high school players during the spring or summer?

I am a high school QB who has pretty good ping mechanics however I need to get into some kind of 7 on 7 league in KC in order to improve my ability in reading and throwing against defenses and in general improving my confidence under center. If you guys don't know any leagues then do you have any ways for me to improve against live defenses. Please help!
