Social Media Content writer // will pay per post Open

I am looking for a Social Media Content writer for my existing business. My primary focus is on Instagram as I am looking for content that has a high level of engagement. The writer should have experience producing content for this platform, have a deep understanding of the audience and be a creative thinker coming up with content that will not only keep my followers interested and engaged but also represent me and my business. My budget is negotiable and I would prefer to pay per post.
