You can start with a blog and start writing articles in the niche market of the product that you plan on promoting.
You can set up free blogs at sites like http://www.blogspot.com or http://www.wordpress.com

However the disadvantage of a free blog is, your blog can be suspended for whatever reason the site decided to. Imagine if you have done plenty of work on it, get good readership and ranking and then all of a suddden, you have it all wiped out. That’s a lot of work wasted.
It’s still better to host your own, you own it and can do whatever you want. But the choice is yours.
Buying a domain name and hosting it is not as expensive as what you think.
If you are serious about going into this, you may want to consider investing a little money into this business of yours.
domain is less than $10 a year at www.godaddy.com
hosting is about $10 a month at www.hostgator.com

http://www.clickbank.com is one that you can start with products that you don’t need your own website to promote. It’s all digital product and opening an account there is free, thus you have zero overhead there.

An good affiliate program that I do know of but will require your own site is one that I would recommend with step by step guide to affiliate marketing. You can watch this guy video for free and how he strategize on how to make $10k a month at

In the end, the final decision is still yours and yours alone.
To you success and good luck
