The answer Creating flyers in LaTeX has a complete code example illustrating how to create a flier. However when I create the PDF the page orientation is portrait instead of landscape. 
Here is a simplified version of the code (with filler text)
\documentclass[10pt,foldmark,notumble]{leaflet}
\usepackage{url}
\usepackage{lipsum} % this package is for creating filler text
