I will try to help you the best I can.
First of all, please know that I am not a fan of affiliate marketing. It's really difficult. You DO NOT have control over the product... or how the customer is handled after the sale... or any of that. But YOU DO all the work.
The first thing that scares me about your story is that you don't have a website. That's a problem. Yes... there are all those guys selling ways to make money without a site... but they have site, don't they?
To start a site... you can do it the hard way... with an HTML editor, or you can get a 'CMS' or Content Management System' like Wordpress (I mention them because it's free... and very popular). With a CMS, you really don't need to know a lot HTML. The CMS does all the 'heavy lifting' for your. You just type and add images. Pretty simple.
The other issue is that you have a real long road ahead of you. There are some technical issues YOU MUST know... and you will have to spend some money to get your mailing list started (about $20 a month... maybe less). But all of this requires a website.
Also... there really are several people CLAIMING to be making big money on line. I can tell you that in 2004, I started a website that with hosting, auto responder (email list service) and all that, my total annual costs were to be about $1,100. I said to myself that if I made $1 more than the costs in the first year, I would keep pushing. Not trying to boast... but the site sold in the LOW 5 DIGITS the very first year. Now, that's not huge. And... I didn't set my goals very high... mostly because the people in the industry told me that it would never work.... and there I was. Today, the sales are several times higher.
So... now, I don't know if I discouraged you ... or if you still want to do this. But first of all... you have to take the step to get a website started.
I hope this helps and I look forward to hearing your reply.
