I see some posts are not qualified as good English especially in grammar. So I think probably some native speakers want to share English lesson. In the first place I think the would just share it with no fee, but since I read their culture that strangers are not friends, so I think probably better to pay fee.
So, do you think the native speakers would share English lesson to you free or with fee?
It could be a good service and profitable if theres lots of interested people. Study your market and see if its worthwhile to start such a service.
Reading the posts in this thread alone, you could tell that most arent native English speakers and they need some lessons. It could also help improve the quality of posts in the forum.
