Webinar scripting

Hello. I am looking to do a pre-recorded (automated) webinar that seems live. It is for a photography, videography, and editing course. I will add 3 videos to the webinar teaching things. I am looking for the webinar to sell the program, sell the upsell for a discount and sell the high end upsell for a deep discount. I have the program to create the webinar and will do the demo videos. I am looking for a great outline and, if possible, the powerpoint slides. What is your price for 30 - 45 minute webinar. Including the videos it will be around 60 min. Thanks! If you want to see the sales page it is [login to view URL] You can also sign up on the page for a free sample of the product if you want.
