All of them use different requirements to publish your book. Formatting can be a real hell on earth for the self-pub author.
Well, I became an expert in finding the right formatting for all these devices.
For just 20 dollars I can format your book for Smashwords (no Autovetter errors!) and Amazon Kindle.
I add a perfectly working, linkable, table of content, plus links to your other books or websites.
