Event Requirements

Hi,
We have a project where we are needing to have a registration system for an event that will have around 500 people attending. Here is a screen shot of our mind map showing the info we will need to collect. (http://ri7.in/PJDf/Screen%20Shot%202013-05-31%20at%2010.08.09%20AM.png – minor_form needs to be a file upload)
The pricing structure is relatively simple: First we have “early bird” then we go to the normal pricing in each of the pricing time frames we have three pricing structures; (Single, Group 5-10 people; Group 10+ people) the ability to calculate the total price as people are added to the group booking would be nice.
Is eWay payment gateway supported?
Does it add attendees to a Campaignmonitor.com mailing list?
Thanks,
Cameron
