So by now you've decided what you want for your book and hopefully started looking at companies that can help you on your way.

So you want an ebook first of all, this is by far the easiest way to publish your book and if you chose Amazon to publish your ebook it doesn't need to cost you anything, check out their publishing site, it will cost you nothing more than your time and I promise you it's not as complicated as it looks at first glance. There are other ways to do an ebook for other companies and I don't know their charges, shop around. Remember that Amazon has a huge percentage of the market and as a new author you can keep your costs down and find an audience all for just a little effort. They also offer a cover design section which is free to use. Hard to beat isn't it. 

The only catch is that your ebook will be exclusive to Amazon but as I said with the amount of the market they command you might pay to go somewhere else but not have the exposure you require. But... do your own homework and don't take my word for it, you might want something different for your book especially if it's a children's book or contains a lot of images.  

Keep questioning everything...
