This is called affiliate marketing.

You should start by learning affiliate marketing, then get an email list to promote to, or rather build it...

You can use a lot of methods to do this, such as creating a landing page that collects names and email adresses in order to keep promoting to them and giving away content etc.

This is not really JV's just yet...

When you start to get a bigger list you can start to promote products and ask them to build your list in return for a promotion, by sending them an email explaining what you want to do...

Say, "I provide content to your list and send a free report and in return I make sales for you, my list is XX,XXX, do you want this?" etc..

And also become friends with them, you know talk to them about other stuff besides business etc.
