What content selling services (audio, video) do you know?

Question

Computer networks

I have video lectures and audio recordings of lectures.
Tell me online services where you can sell it?
On the example of the plati.ru service , I start the content, and after the user has paid, the service immediately gave him the content.
Preferably local services, so that payment systems are as convenient as possible for users of the CIS countries.
If this is a service with the ability to build it into a self-written engine, it will be generally agony :)
Thank you.

Didn't use it, but apparently what you need.
