Well, I think first you should buy some vocabulary and grammar books for beginners and then check websites like talktomeinKorean. If you have some questions during your study, you can always post a question on italki or other websites as wordreference.

I recommend checking out http://www.talktomeinkorean.com/

The site has a free curriculum of beginner to advanced Korean podcasts with PDF notes.  I do not recommend using their 1:1 lesson system because it is less transparent than italki.
