A Website needs to be build

I need a website for my life coaching business which in design sense should be of global quality, like [login to view URL] or teslamotors.com. A system needs to be developed in such a way, that a guest user will able to see the upcoming webinars and in order to attend that webinar he/she needs to pay an amount for it. Not only they can attend that webinar, but also have access to the video of the webinar for later viewing. Written content will be provided by me. Rest of the details will be given after we discuss the project personally.
