Does Wowza gives services for online classes?

hello there,
we have a custom website for logo designing services. However, now we are thinking to offer the online designing courses which will be stream live. I have been assigned to find the best service provider, and after the research, I have found many good reviews about Wowza. Could anyone help us to know more about them? And how much it cost?

About the same question was asked for the same website yesterday: Can we use Wowza's services for our website?
