Have some advice worth paying for as a start.
First you would need to show qualifications for the type of advice your offer, and preferably a list of work experiences that can be checked at source. Then you would need to take out insurance in case any one sues you if your advice proves wrong when they follow it to the letter. And then you would have to set up a website, with advertising links, and some means of online payment, probably via Google or similar.
Maybe go work at some hotline.
Pay me and I will let you know,
Try KPMG for options. That's what they normally do for a living
I don't think teens have money to pay for advice. But if you figure it out, let me know!
