Administrative tasks online

I need a person or company willing to perform various administrative tasks online.
These tasks could include populating wordpress blogs with pre-written content, setting up social media accounts, uploading pre-recorded videos to YouTube and other video sites, finding images and posting them on relevant articles, commenting on content, and more. This project will be on a long-term basis. Paid tasks with pay increases negotiable after performance assessment. Must be able to communicate via Skype.
