X32 Producer Streaming

My Church has an X32 Producer by Behringer. I'm going to video someone in via live video conference. I'm using my laptop to conference them in. I need to run all audio through the board, so that it's heard in the house. I need a mix for the incoming audio and another mix to go back to the person being conferenced in. 1) I also need to be able to livestream services to youtube/Facebook. I need listeners to be able to hear the band, choir and preached word. Can anyone help us?
