Answer

Well, you need to get a book
http://www.amazon.com/Integrated-Korean-Beginning-Textbook-Textbooks/dp/0824823427/ref=pd_cp_b_3
It's well-written and easy to follow. I recommend the workbooks you can buy with it too.
Or you can find an online teacher on italki
Best of luck! I found that its important to make Korean friends and try to talk with them when I was learning Korean ^^
