Social media manager

Hi Freelancer! www.creafree.org is looking for someone with experience and knowledge in social media management to take charge of my business's online presence. I would need help managing and overseeing our presence on Twitter, and I have a specific goal of improving our online presence. The person should be comfortable creating content, but also using content I provide for posts. I am looking for someone who has great communication and organization skills, and who has an eye to keep track of the latest trends in the online market. If this sounds like something you can manage, I would really appreciate your help. Thank you.
