Just FYI, but my dad has a book (non-fiction) published by a 'real' publisher in paper, sold 200 copies and his publisher was thrilled. For a new author, the expectations are just very low---no matter if it's indie or not. Imho you simply can't go into this expecting that it will be the instant path to fame and fortune. It just doesn't work that way, and there isn't really a way to *make* it work that way simply because you are competing in a very crowded marketplace for people's eyeballs and attention, never mind their money
