Virtual Assistant

I'm looking for an assistant that can help us:
1) Manage and grow our social media followings (We have 80k+ on Facebook alone)
2) Create interesting graphics for YouTube video thumbnails, article featured images, Instagram, etc.
3) Do very basic video editing
4) Transcribe YouTube videos
5) Conduct customer and prospect research
6) Conduct podcast and guest post research and outreach
7) Many other ad hoc tasks

Other skills such as a basic knowledge of WordPress and SEO would be great, but aren't necessary. There will be many opportunities to grow and learn with this role.
