there is already a pdf of the book on the linked site. how is yours better or different? i'm not a kindle user, so i don't know the details.
Kindle does not read PDF as a native format. Instead, you can send the file as an attachment to a kindle email address and Amazon's server converts it into the azw (originally mobipocket) format. This the file on offer and getting it direct saves five minutes. (Thanks for the offer!)
