You could also easily do this via a YouTube channel or FB live. All you need is a cell phone, a tv set (preferably a large one) with internet access, and anyone can set up a YT channel for free. If your guild already has a FB page, the live feeds can actually live there so members can access them later, or catch up if they missed it.
Pros to the tv screen - it is easily visible in rooms that are not darkened. Cons - screen might not be big enough for everyone to see. You could get a projector and screen somewhat inexpensively, but that kind of setup needs dim light to be easily visible.
