LibriVox.org is a great website in my opinion. It doesn't offer lessons, but it has a huge variety of audio books. Next time you want to read a book, try listening to the audio version while reading it. It will help with pronunciation. You can also help others by uploading your own reading of a book or a novel.
You can find some here:

Youtube is a good source too.
Unfortunately I can not mention sites; the issue is outside my concern, and I believe in creating my own audio lessons and present them for the students in the class. That was what I was doing; now I'm not working as a teacher.
