Looking for a good livestream setup/ software.

Currently I run a video production business and I'm interested in offering a livestream service. I want to do multi-camera sports shoots, Speeches, award ceremonies, random events... Anyway, I want to ensure the quality remains professional, the stream is easily accessible to viewers, and a basic stream could be accomplished with only one or 2 people. Ideally I'd like to stream to Facebook and or YouTube, but I'm not sure how those streaming platforms would support a multi-cam set up. Any advice or suggestions? via /r/videoproduction https://www.reddit.com/r/videoproduction/comments/5fnadg/looking_for_a_good_livestream_setup_software/?utm_source=ifttt
