Thanks to Amazon, independent publishing (or "self publishing") has never been easier. Amazon Kindle Direct Publishing (KDP) allows you to publish and sell your work through the Amazon marketplace. The hard part is creating the material, designing the book cover, and marketing the finished product.
I found the website to be very intuitive and packed full of very useful information, informative videos and a forum. Amazon KDP does offer templates - for designing your book cover (or you have a choice of Amazon design selections), for your manuscript for print versions, and an easy platform called "Kindle Create" to create your Kindle version.
I am really cheap. I didn't want to spend any money on vanity publishers, nor did I want to spend any money on professional designers to design the book cover. My cover and illustrations do look cheesy. I am not a professional designer and illustrator, and I guess it shows. But it least all the content is mine.
