Simulated Webinar Viewers

I will be hosting a webinar. I currently have 4 people reserved for the webinar. I would like these 4 people to feel as though the webinar has 50 people on it. I will need you to create or use 50 e-mail accounts that you control to register for the webinar. Then, I will need you to find a way to log on to the webinar with all 50 accounts at the same time to make it appear that there are more people viewing the webinar than there actually is. All 50 accounts will need to stay on the webinar for an hour until the webinar ends. Before I hire you, I am looking for a detailed description of how you plan to make this work. Thank you!
