Hello,
I know you desire someone who is a native of the countries mentioned. I am not but English language is the official language in my country and we're taught in English in all of our school. I have a personal knowledge of the language and could teach, instruct and coach in English language.
If you don't mind, kindly consider me for this role as I promise to deliver and give my best to this course. I am available to begin immediately.
Thank you and warm regards,
Otee A.
