Captive portal for guest network to capture user's name etc. on Cisco WLC?

Hey folks,

I have a Cisco WLC 2504 and am looking to set up a guest network. What are the best ways to go about creating a captive portal that will ask the user to provide their name (or any other information) and accept an Acceptable Use policy? Ideally this information would be able to be viewed on the back end to link up with their device MAC address, device type, what IP address was assigned via DHCP, etc.

Any ideas?

Thanks!
