Author tells why it was easier, faster, and can have bigger payback going with epublishing

Since professionalism is essential, we hired a cover artist and an ebook formatter. A publisher providing these services takes 52.5% of an ebook’s cover price, and the retailer gets 30% through the agency model. That leaves only 17.5% for the author. By absorbing these sunk costs ourselves, we’re able to earn the full 70% royalties and not have to share them with anyone. Though we’re splitting the profits four ways, we’re each earning only slightly less per copy sold (51 cents each) than we would on one of our own paperback books (64 cents each), and still only charging the reader $2.99.
