You know, one of those people who write sales letters for a living? A really good copywriter can make $500+ per sales page written. I got my hands on the rights for a fantastic ebook all about how to write really great copy.
If you can write really great copy you can literally print money. The ebook course I have available for a $9 donation is 16 chapters long 87 pages long.
If you have any interest in freelance writing for a living, this is the way to go. You will make a lot more money writing great copy than articles.
