Affiliate Marketing Secrets

i would like to earn quick cash, and at the same time realising that my only niche/ top potential, is to conduct hometuition. i would like to teach primary school math, oh and perhaps because i have seen the so many struggles that psle students faced in math, so had like to help them, but i am only a secondary 4 student, i dunno if people will think that i am not cu out to teach them. but i had like to give it a go. where and how do i get started, any tips on how to get the news circulating so that i can get my first student?
