Tutiorial Screencast Videos for Website

Hi, We have web based leaflet tracking application www.leaflettracking.co.uk. The application is easy to use but requires a number of 2-3 minute videos showing customers how to logon, run reports, where to go to watch live their distributors, create customers and users and also show how to create areas, boundaries and leaflet campaigns. The video have to be professional and have a neutral voice over.
