Social Media strategy and business needed for a new website

We have a website that will launch soon, [login to view URL] [login to view URL] is a website that has all important information for people in the investing/finance business. For example, I am an investor. And I want to invest in solar energy. Then I would go to this website to find more information such as where to invest, who do i contact, and things like that. So, I want to get more followers on Twitter and more likes on Facebook. I want to get REAL people that are interested in the website, not FAKE accounts. What is your strategy for me? What previous work have you done that is similar to this?
