There are quite a bit of good covens on this site. I would suggest looking through the covens listed under the groups tab. Read through their profiles and decide which one most suits your needs or offers the information that you are most interested in.
You might also want to chat with the coven leaders, council members, and so on to see if they are knowledgeable on the topics listed, and if they would be willing to offer you assistance and guidance on those topics.
This of course is just a suggestion. If you search the covens, I have no doubt that you will find one that is everything you are searching for.
