Did any one buy parrot training videos from like chet womach or other people?

Please recommend me some videos or online membership site where I can learn more about how to train my pet parrot. Thanks in advance.

I was wondering if they were any good and worth the time and money?

We are willing to pay. We have a 6 year old African Grey Parrot we adopted from and abusive family, and it has MAJOR biting problems. It’s just down right obnoxious. We already looked at Nathalie Roberts training videos so please don’t say those. We want her to stop biting, learn new words, and maybe even learn a few tricks. If you could tell me the best videos that would be great!
