Social Media Rockstar - Help Manage Instagram, FB, Twitter, LinkedIn for a Huge Community Launching Soon

I need someone preferably versed in social media and ORGANIC engagement to spend a few hours a week helping me grow my NEW brand launching this Friday, Content Hacker. I created an Instagram and would like a heavy focus there. I will create all the content, I have a huge content agency that produces it. So you will just be MANAGING, boosting engagement, working hard to grow our presence on social media. I'd like candidates to show proof of growing communities. Above all, be humble, a team player, and willing to put in the work!
