(Potentially Long-term) Looking for a Content Marketing Writer

I am looking to establish authority and to drive organic traffic to a niche website. Your target audience will be musicians, creative writers and artists (Bonus points if you are one). You know how to tap into the reader's mindset, their struggles, desires and how to stir up emotions. You are comfortable with keywords and writing practical, tangible advice/results while being simple and concise. Depending on your familiarity on the subjects, amount of research may vary. (I may be able to provide research material if needed.) (Must be plagiarism free)
The first piece is estimated to be around 5000+ words.

In your proposal, please include:
- your rates (words/hour, $/hour... etc.)
- Experience (Sample)
- Timeline

Thank you.
