Why not offer it for free for a set period to see how it goes, once you have either past the period or sold x amount of the books, start charging. Or offer it for a small amount on sites like smashword?
That's just me as a non-writer / non-publisher talking. I'm sure there are heaps of people here on the forum who had the same problem and will be willing to share their experience
