Leave the character's name blank and create a file in which you can drop in the name and other characteristics.
Break the story up into sections to be illustrated.
Illustrate the story. You may want to have a variety of illustrations that allow you to change the hair and eye color of the main character in the story to match the child who the book is personalized for. You can create several combinations of hair, eye, and skin color and save them as separate files so that you simply match the illustrations to the descriptions from the client.
Choose an on-demand publisher to produce the orders as they come in. Look for a publisher that has an easy upload system and that will you to upload separate files at a low cost to you.
Advertise your book online, in children’s magazines, and at local bookstores and craft fairs. On your advertisement you should include the premise of the story, the items that you will personalize, and the cost of each book.
