I know a little private language school in Beijing where I have been twice myself. I don't know whether one of these teachers is able to teach old chinese -maybe not- but I think they certainly can find a good one for you. I also think they will be willing to help you. You can contact me here if you want their address. Wish you good luck!

夫古文隐晦艰涩，彼华人尚望文兴叹，尔异域pipio,安能知要其中？况古文之不行也久矣，知其不可而强行之，无益。

I m Beijing boy and I m good at Authentic Beijing speaking.Feel free to contact me dude.

我在北京，打算从事对外汉语教师，不知你学古代汉语是为了学校考试？还是个人兴趣？如果有意向，可以联系我.
