I would highly recommend a small publisher such as Starry Night Publishing in Rochester, NY. For less than $300, they take your Word Document, edit and proofread it, compile text and pictures, convert the files to the proper formats for eReaders such as Kindle, Nook, Kobo, iPad and PC, design a professional-looking cover, take care of Copyright and ISBN, handle marketing and distribution on Amazon, Barnes & Noble, Books A Million, Abe Books and many other online retailers, give you writing tips, allow you to retain 100% of your rights and give you all of your royalties. They have published more than 300 books in the last twelve months, with only satisfied customers. Most books are for sale on Amazon within 48 hours of submission. They do paperbacks, eBooks, CDs and DVDs. Check them out and give them a try.
Their website is: starrynightpublishing.com
