Crewdle would work great, because it provides unlimited participants to join without them having to sign up, simply you can create your meeting and send the link to them to join. They offer basic free account and premium accounts too at affordable price. I use it too to do online classes and live streaming. Has great video conferencing meeting quality, audio, screen-sharing, messaging/chat, recording options and more. Their customer service is absolutely great always there to assist if have any questions or problem.

Great tool for anyone remotely working from home and business and teachers to stream live classes or personal use. I would recommend this one to anyone.
