Super Packages and the Web!

Hoping for some ideas/suggestions on how to make our first dabble into super packages work online. I am fine with the set up, etc for selling through box office, but a little lost as to functionality when it comes to getting them on the web. We are going to be offering fixed seat super packages and non fixed seat flex packages. Just wondering how easy this is going to be and what I need to be telling our web people! We LOVE the set up that Opera Philadelphia have (pretty much offer everything that we want to offer) so if there is anyone from that company that would like to chime in.....but welcome any suggestions from anyone that has done this!
