Writer, Virtual Assistant, Social Media posting

I am in search of some one that can help launch a subscription course that is a companion to a published book. This is going to involve research, creating content, blog posting, social media and some general assistant tasks.
To be considered for the job you need to be able to write English very well and have an eye for marketing copy and creating content that can be uplifting.
There is a course site that is being developed and some material needs to be created to accompany the course and for social media.
Attention to grammar and punctuation is important as well as an attention to detail.
