Sorry I don't email people on the board.
If you want to know the basic template I use for LaTeX ebooks, for a 90mmx120mm screen, I'd probably just use this:
Code:
\documentclass[12pt,oneside]{book}
\usepackage[papersize={90mm,120mm},margin=2mm]{geometry}
\usepackage[T1]{fontenc}
\usepackage[charter]{mathdesign}
\usepackage[normalmargins]{savetrees}
\sloppy
\pagestyle{empty}
\usepackage{titling}
\title{The title}
\author{The author}
\date{\today}
\usepackage{hyperref}
\hypersetup{pdftitle={\thetitle},pdfauthor={\theauthor}}
% additional packages as needed
\begin{document}
\maketitle
\tableofcontents
% ... regular LaTeX stuff for the book ..., possibly tweaked if need be
\end{document}
But adjust the page size to the exact screen size of your device, if possible.
