A few examples of conertina book son Etsy and their price range. There is a big different between some of theses, and it makes its really hard to price my books. The 20 page on just above is very cheap compared to the 6 or so page one just above it.
Obviously the hard bound ones are a lot more, but even still I think some of them are way to expensive.
