Need 25K twitter followers

I would like 25,000 real, legitimate, twitter followers. I work in social media so they must be 100% verifiable and legitimate. No fake profiles, must be able to retweet if necessary. My company can tell if I have fake followers so they must be real profiles, and not all the same. Most (but not all) followers should be from the United States. ALSO, they can't all happen at once. Please PM how you intend to accomplish this... White hat methods only.
