Make Money Responding to Emails

You can start a website where users can charge others for giving them their valuable time and get back to them with a response.

This can be useful for famous and busy people and the paying for a response will certainly filter all the noise.

A normal person can speak to Bill Gates and get a response. Or a fan can write to Eminem and get a response.

Or an SEO expert can reach bloggers asking them for backlinks.
