The Indie Author ATSO Guide Volume 3: Starting From Nothing
Being an independent author is a fine art, and as with all artistic endeavors there is no guarantee of success.
But there are certain things you can do to increase your chance for success.
Here are a couple links that provide some nice information, but please note that I do not recommend buying any course because I think that if you dig hard enough almost all the information can be found for free on the internet. Also I do not recommend every single piece of advice in the following links, use any of the advice at your own discretion.
This is a nice video with tips for indie authors, Mark Dawson gives advice on starting from nothing in one of the topics.
