Profession Audio/ sound quality for a commercial?

OK, I see these amazing national commercials where are a ton of natural sounds going on throughout the spot and the main talent sounds amazing. Or maybe the wind is blowing like mad and once again, the Talent is clear as a bell.

How do they do this. I HAVE TO KNOW. Right now, I'm at a point where this is the only thing that really limits some of the work I would like to do.

Is there a book, a video tutorial, something? Anything I can do to try and learn this trick of the trade? Every time I type in a google search, I just get a ton of movie SFX junk.
