Multi Media Presentation Tutorial

I need between 1 5-7 minute long video chapters to introduce our new Project for our soon to launch website, how to sign up and how to use it. Each video chapter would explain the use of each part of the process, so it should work as a standalone video. But at the same time all chapters should be natural to watch as one long video. The video should be attention-grabbing and cause excitement in viewers. THE VIDEO MUST HAVE: - Attention grabbing / Not boring to watch - Cool opening and ending animation - Quick sentence to explain each step in the software
