Well, it’s definitely possible however extremely difficulty and a LOT of hard work. However, if your still hell bent on giving it a go for free then I will tell you how you can do it.
Firstly, you need a product. So what’s something you can create for free that won’t cost you a cent? An e-book? Or if you have know-how perhaps a software program?
Now that you have a product to sell you’re going to need a website. Free web hosting that doesn’t have any ads and has a short url is at: http://95mb.com . The last thing you want is a bunch of ads running up and down and through-out your website (this will most likely turn your visitors off).
Once you’ve prepared your sales letter next step will be to prepare to take payments. An automated “free” option for expecting credit cards online is paypal (oh it’s a nifty little tool I tell ya ;-) )
Now you’ve got your product (that you created for free), free web hosting and a free merchant account so you can receive automated payments, what’s next? Well, you won’t be able to sell a darn brass razoo without any visitors! So how can you bring potential customers to your site without paying for them?
