I have published two books now for friends. They wrote them, I proof read them and saved them as a PDF. I then went on to an internet firm called lulu which is a free publishing service. It guides you through each step right through to adding isbn numbers and bar codes. It even prints your cover with a price on. At this point it is free. You get told how much your book will cost for them to print, but you can charge what you want for whatever profit you want. As the maker of the book you get to buy it at the cheapest price. It adds it to amazon for free.
The book is perfect and is well produced. All you pay for is each book you order. So if you only want one printed then you only pay for one. It is brilliant and I have sold over 1000 books for friends for charity this way.
I really can't sing their praises enough so if you have ever wanted to write a book, do it. It may well catch on and you could be a millionaire!
