Contact Form 7 add form based on condition

I have to create a page that contains conference registration capabilities for people. The problem is that they will need to provide multiple pieces of information on each attendee. So, I need to be able to provide the capability to allow multiple registrants at one time (up to 12), so what I’d like to do is create a text box where the user would type in the number of people they need to register and that would determine how many times the form (per registrant) would appear on the page. That way if someone needs to register 1 person they don’t have to see the form 12 times. All of this information needs to be saved to be passed on as an email message. Is there a way to place a condition on how many times the form shows up on the page? I can create up to 12 contact forms and label them 1,2,3, etc., I am totally new to this and really need your help in figuring out how to do this.
