Hi - on your lulu questionn - mostly free. you can publish for the price of a "copy" book for you to edit over when you are done. You pay the "cost" price for this book only and of course s/h. If you do your own cover, editing (get a friend to help, or two) they offer free "gidgets" for websites and a free storefront you can place your book on with a web address people can click onto, forums, intrest groups to join if you want, you can do ebooks as well... you set your own price above their cost and that is your royality money, you can purchase pr packages as well...
once you download your book you need to check the email they send with it - I have to play with settings a bit to get it to look right - I do not know if other companies work this way or not
one drawback is you do not get any free books with this option - you might if you purchase one of their packages?? I am not certain.
my storefront is stores.lulu.com/kayscreations if you want to look at it to get an idea. They have a few different backgrounds and layout options you can play with - I kept mine unisex - most men feel stupid clicking onto girlie pink pages and my book is a sci-fi.
Hope this helps some
Kay
