starting an esl club at my high school

hi! i’m a sophomore in high school this year, and i’m very interested in international relations and languages. i also want to set myself apart as a leader at my school and for college applications. i was looking to start an esl club with another friend, where we could instruct others in english and give non-english speakers a place to practice in conversation. i was curious if anyone had experience with a club like this or general advice on how to make it happen. thank you!
