Geoff Shaw is no longer accepting new people to his Kindling Course. I have spent time finding an alternative course of similar quality and feel happy to recommend Tom Corson Knowles Course on Udemy.
As you can see it is a best seller and has excellent reviews. Tom is a young writer who has done extremely well and I have been a follower for a few years now. If you’re interested check out his course here.
You might also be interested in the platform Draft2Digital. It has been growing in popularity and has lots of great resources for publishing both ebooks and physical books. If you struggle with formatting then this could be the solution for you. Its free to join too! Just one thing to note – if you want to publish kindle books on Draft2Digital then you must make sure they are not enrolled in Amazons KDP select program if you already use that.
