English tutor for elementary level or primary school

I am Katherine, 45 years old from Bochum. I am a graduate of Communication and Journalism. Originally from Uganda but have lived in Germany for the past 17 years. English to me is like a mother tongue since i have done all my studies in English. I have no professional experience in tutoring but on a personal level I have been the first English teacher to my 3 kids. The first 2 kids are in an English bilingual Gymnasium (Neues Gymnasium Bochum) and my 9 year old son will join the same school in September this year. Their grades in English are always a 1 through out. This is evidence that i know how to support kids to excel in English especially in the Primary level. I need this opportunity to help me do something challenging but highly rewarding at the same time. Looking forward to your positive reply! Best regards.
