Help needed: is this virtual seminar designed properly?

I'm a marketing consultant working on a virtual seminar project aimed to attract 30,000 attendees. Can i ask everyone to see if the registration process makes sense? i mean i'm not sure if the subscription style makes sense here to registrants.
