I don't know of a site which will tailor all the components to your liking, but like I said, you can find articles on mixing as a whole or about specific components, for free and make your own textbook.

And of course you could buy a book.

Keep in mind, with any DAW, you have almost all the processing effects you will ever use and you can experiment and learn in that way.

If you wanted some experience in mixing for a client then I would go to college.
