What equipment is needed for this kind of setup?

[Castle Party Rentals]

I work for a party rental and entertainment company and would like to start offering the making of music videos live for my customers in which I could burn a DVD for them to take home. Here is an example of the setup:

What equipment is needed for this kind of setup? I know I can get all the chroma key stuff from tubetape, but what about like cameras, computers, dvd burners, etc. I can't figure out how to efficiently structure the setup so that I could print the DVD in a relatively fast manner and not have to BS with too much editing, etc.

Thank you for your help!

It's nothing more than a DVD recorder plugged into the output of something that I've seen since the 80s.

Not sure how to set the live green screen work up --- ask a broadcast teacher at a local college.
That person will know.
Don't ask about the DVD part, that's idiot-proof. It will just confuse the question.
