Number 1: use Pronoun. Com They will distribute your e-book to Amazon, Apple, Barnes & Noble Nook and KOBO Canada. Write up an attractive author page for Pronoun.
Number 2: use Smashwords.com They will distribute out to a custom list of book suppliers. Be sure to remove off the distributors from Pronoun so you don’t duplicate (and confuse!) those vendors.
Number 3: Use Draft2Digital.com They will also distribute out your e-book and will take a cut on every book sold. It is a big reach so be sure to use it.
Number 4: Get over to IngramSpark.com
You will need to have your book formatted for print. Even if you have no intention of selling a printed book, you will still need 25 printed copies for reviewers. I have not found an easier, cheaper way to do this than IngramSpark. Ingram will distribute out to all non-Amazon vendors. There is a $49 fee for getting your print book set up.
Number 5: Go to Amazon Kindle Direct Publishing (KDP) and get your book up on there.
This is specific to Kindle only and there should be no fees.
Number 6: Go to CreateSpace.com and get your print book specifically set up for sales on Amazon.
See if their print copies are cheaper than anyone else for the reviewers.
Number 7: Go over to BookBaby.com and set up a $19 printed book.
Do you think your novel is perfect right now? Get it printed, hold it in your hands and have another look. You will find more mistakes. Everyone does. I do this with every book. This is the hardest, bone-head lesson I have learned in writing.
Number 8: Go over to EBookPartnership.com.
This company in England and its employees are very good at worldwide distribution. Their services start at $299 and go up. You are paying for professionals and a world-wide network. You will need a thick skin because they don’t sugar-coat anything and don’t hold back on where you can improve. You want no doubts about your book, use them.
