Create Training Guide

I have client who has created a web based cash flow tool. He would like to create a slick, profesional training guide for prospective users taht would walk them through the use of the tool. The output should ideally be a pdf or powerpoint document although a java tool would also be consideed. the tool is a web based, interactive calculator that is pretty self explanatory already. The idea is to make something comprehensive enough that people new to the concept of business cashflow will understand how to use the tool. I can provide detailed explanation of how the tool works and a link via PM, you just need to make a simple and profesional, self explanatory, training guide. Preference will be given to poeple who submit a sample of something similiar ie a profesional training guide on any topic. Thanks, best of luck
