iPhone application (Small book)

I would like a small iPhone application created for me, UI is as simple as it gets, and the Content will be provided by me the book is currently divided into PDF's, text version (or any other) will be provided if needed. my main concern is how to give this whole book, but not to force the user to download 100's of megas.. (pdf's are hug) i would need your idea on how to solve this together with your price offer. if you want an idea how i want the APP too look and feel watch [login to view URL] p.s. the book itself will be in Hebrew as written in the above example, but you'll have no need to understand or worry about it, i will divide it to chapters and do whatever is needed for your assistance.
