You can learn a ton for free from Neil Patel if you have the time to implement his advice. I'd recommend reading some of the articles on his site and putting them into practice: http://www.quicksprout.com

You can also subscribe to his email courses and ask specific questions in his recently released Traffic and Conversion Forum: http://www.quicksprout.com/2013/09/03/introducing-the-traffic-and-conversion-forum-by-quick-sprout/

I don't work for Neil or have any affiliation - I've just been impressed with his credentials and found his advice to be incredibly valuable.
