Can anyone help me with some basic information...I like to run a Live strean with 1, 4, 6 and 12 hours delay. how can i make this possible the BEST way using wowza 3 or 4. Please advice.

I heard abou ndvr and live stream recorder. but please advice on whats the best method possible.

Also if i like to hire someone to set this up for me... please advice if wowza support offer to work side by side with customer to setup wowza for my specific need for a fixed fee ? or can recommend a developer.
