Convert a Template to a Website -- 2

Dear all, I have built a course registration website on wordpress. I need a add-on or plugin that allows customers to register for a class. There should be the usual event name, description, start date, end date, start time, end time, map, MAX attendees per class (whereby it will say it is closed due to the full class), cost per class, cash/cheque/credit card payment. During registration, basic questions will be asked like name, id number, company name and no of tickets . In addition, a guest should also be able to do multiple attendee registration. for example, Guest A signs up for 5 slots. There should be 5 forms for individual name, id number and company name. It is something like Event Espresso Pro, with Multiple Attendees Registration. Hence there is also a calendar display with different category of events. And also mobile responsive. Thanks!
