Need help: There are sites for organizing courses?

Here, let's say I want to hold courses for cooking scrambled eggs. I make it super and I want to share secrets. But for the money. Is there a service where I can recruit people via the web, at some time broadcast to them using the webcam process, answer questions? And so that they still denyuzhek paid me through the same site.

I searched, but have not yet found anything worthwhile. I found software for remote control, but it requires a server, but this is not the case. It’s just that you don’t post it on youtube either, I want to make the lessons unique, and there’s no way to restrict access, and no interaction. About the payment, I generally keep quiet.

In general, if anyone knows such a service, please share a link.
