Flexible tutor most capable of teaching English and perhaps Mathematics for children in younger age groups

I am currently studying a Masters in Finance and Business Analytics, with 5-6 years work experience where the majority included preparing English writeups in terms of corporate documents and news releases, as well as using basic Mathematics for financial and investment analysis. I do not have any relevant teaching experience, but once volunteered to teach and help young students at a student convention programme. Hope to get the opportunity to try out teaching and hopefully be a positive influence to as many young students as possible.
