An easy wordpress webinar and prerecorded event plugin

I want a wordpress plugin that allows for a registration landing page, name and email input, along with a choice of dates and times to choose (or to view prerecorded session). I want to be able to use google hangout for live, or youtube or amazon s3 for prerecorded videos. The registration I'd like to utilize the subscriber feature in wordpress, capturing their data for this event and future invitations. I'd like the registration to also have the ability for a short video message and yeild a thank you page, also possibly with a recorded message and possibly a downloadable gift for registering and the ability to post a bonus gift if they share the event on facebook. Then I want them sent an email confirmation with a link to the webinar. Before the event time, I want the webinar page to show a countdown timer to the event. The webinar page, showing live or prerecorded video, I want to have a chat window that corresponds to an admin chat on the wordpress dashboard, in the plugin's tool area for events. But, if it's a prerecorded video, I want all questions sent to me by email and the ability to respond by email. This could use the wordpress comments notify and respond function already built into wordpress. Amazon s3 allows the ability to host a prerecorded video and play it real time. Meaning people come late, enter at the point where they came late. Instead of youtube, where the video would start from the beginning if they came in late. I also want the ability for a call to action button to show up at a chosen time and place in the event. This can be a buy button or some other call to action button. After the webinar is ended, I want the attendee to receive an email thank you for watching, with a link to view a replay and an offer to share it and to see other webinars they might want to register for (that are in my list of active webinars and checked as public) So in the plugin there should be active and inactive, public and private selections also. There are a few plugins already existing, but not with all the features I want. Easy webinar plugin is the best and you can see screen shots etc at www.easywebinar.com. WPWebinar is another. I want a product very similar to easy webinar with a few powerful differences. It must also be responsive and mobile friendly. Most of the available solutions force the use of an email system like mailchimp, constant contact, or aweber. While I'd like to have a selection to use whatever code for the registration box, I'd also like the default ability to use my wordpress site's subscriber function and onboard email system. This will allow the data to stay with me and not in a service that can cancel me or that I need to pay extra for. If you feel that you are able to achieve this task, please respond. The wordpress engine already has much of what is needed. Along with the Amazon s3 and google api it should be fairly simple for the right programmer. As mentioned, easywebinar is very close to what I want. But a few tweaks and I can have a better product.
