Step 1 – Write out your book in a word processor such as MS Word. Your finished book can be anything from a few to hundreds of pages. Don’t worry too much about spelling and the layout. You can (if you wish) hire somebody to edit your book into a more professional looking layout later on.
Step 2 – Get your book proof read. If you are going to give it away on your site as a way of getting people to join up you might want to stick with your spell checker. If your e-book is going to be business related or read with a view to selling other items you may want to get it professionally proof read.
Go to Elance.com and hire a proof reader there. Make sure they proof in your chosen countries version of English (US or UK). Expect to pay around $10 per 100 words.
Step 3 – get your book laid out by an editor. This step is optional but the finished version will make an impression on your reader. Short motivational e-books available on some of my sites I laid out myself using automated software bundled with the word processor.
Step 4 – get an e-book cover designed for your e-book. Again, this is optional. You can find free software and do it yourself or pay a graphic designer to do it. Budget for around $50 for a simple cover. Use Elance.com again.
Step 5 – post your book on your site for sale or for free. Track how many download it with shopping cart software such as that on www.paulcart.com
Best of luck.
