Few changes on my site

Hi, i have a site that required some update. Here what i would like to do. - I need to have a new field when we create a movie, This field is a email. So each time a movie has been rent or sell the admin received an email, so i need another person to be notified. This person is the email i will have enter in the field. - i need an option that will allow me to rent a free video - when the site open, their is a video, i need to be able to make it play up to an hour. Need to have some advice to enhance the quality of the movie. If you have any question, feel free to let me know, Need to start the project now, thanks Alain
