Hey there,
Quite honestly you'll need at least $10 online. Hosting & Domain is $20, but I'm sure if you did some looking around you can find someone with an affiliate coupon to get the first month of hosting free.
Next would be the autoresponder that cost a whopping $20/month, but you can get the first month for free if you use a service like Aweber (or any other autoresponder service out there) Then the steps are pretty basic.. Just create a squeeze page that gives away a free product to them (Video series, PDF, eBook, etc.) for when the signup. Then when you setup your squeeze page have your "Thankyou Page" be an affiliate product or your own product that basically says "hey, if you really want to learn more about this stuff you can upgrade right now for $10 or $50 (depending on your niche) and I'll give you my deep secrets on how to skyrocket this thing" and that way once they signup they have a chance to buy your product.
Next you want to have that autoresponder setup to go. If you're beginning just stick to 5 emails that gives little tips and tricks to them and at the 5th email offer them that little $10-$50 product again because at this point they'll have got to know you much better.
I'd say just leave it at that if your just beginning. All you need is 5 emails to make a small sale like that. You eventually want to sell them your absolute everything product for like $1,000 (that's where the money is), but don't worry about that. The last thing you want to do is #1 overwhelm yourself in the beginning and number #2 stock pile a huge number of emails that eventually lead to a $20 sale.. That small sale should just separate the people on your list that are buyers to the ones who are not buyers.
So just create your free product and create the squeeze page and create the autoresponder series that's 5 emails long leading to a small sale.
If you don't mind putting in actual work you can always go online and find people who are just starting out in a niche and offer to train them for free and when it comes to the things that they NEED to buy tell them your only thing is when they end up buying that one thing that they purchase through your affiliate link.
That's what I did when I first started in internet marketing, I coached people for free, but when they needed to get hosting, domain, autoresponder, I just said when that time comes I only ask for you to signup through my affiliate link (it doesn't cost them anything extra anyways) so most are more than happy to do that
Hope this helps
Adam
