마감 Native speaker English tutor

I am looking for a English native speaker who can’t speak Korean. Because once students know that you can speak Korean, they won’t try to speak in English. My hakwon needs to register all teachers. So I need someone who is okay with it. (College graduate & no Visa problem) The teaching style will be 1:1 free talking (each student has 10-15min interview) or playing a game in English.
