marketing for virtual call center

I am looking for marketing services for my virtual call center, and I specifically need Social Media Marketing. I don't have any social media profiles set up yet so I will need them created and managed. My target audience for the call center will be Business-to-Consumer (B2C). I am looking for someone who will be able to help me create a marketing strategy to reach my target customers. The services I am looking for include designing cohesive campaigns, designing advertisements, managing the related accounts and creating content, track and analyze results, and provide ongoing account optimization.

I am looking for someone who can offer the highest quality services, within the given budget and timeline. This person should have successful experience in developing and executing campaigns that are tailored to B2C markets. I also need expertise in social media analytics and optimization, as well as customer segmentation. If you think you can fulfill these requirements and help me with my virtual call center, please submit your proposals.
