English tutor, can teach children of 15 and below year

I am writing to apply for the part-time English tutor position. I am 34 years old and an Architect by profession. Although I do not have formal tutoring experience, I have strong command over English grammar and academics. I can help students understand grammar clearly, complete their academic syllabus and homework, and prepare tests if required. Also I am ready to give trail sessions if required. I would be happy to discuss this opportunity further.
