Online Conversation Partners: A Solution

Are you learning English? Do you want to find a native English speaker to talk with online? Would you be willing to pay a small amount to talk via video chat or to go over homework?

What do you think? Is it hard to find English conversation partners online? How much would be reasonable for an hour of conversation with a native English speaker?

I am thinking of setting up a language exchange website and would love some feedback and to hear your opinions.

Thanks
