It seems that I can`t find the site, but while searching I found something else. Like this one:
http://www.lulu.com/services/pre-pub...versionservice
They charge more for more pages. When I saw that I thought that I don`t know exactly who does the process of conversation to ePUB or other formats go. I`v been using Calibre I thought that after that I just need to find some errors and that`s it. Can someone tell me why do they charge more for more pages and maybe some more detail on how this conversation works??
