Adding Descriptions to Wordpress Blog

Hi,
I have a 3D model download website built on wordpress. there are no texts just a download button shortcode.

URL: https://3darts.org

I need someone to write 150+ words to each post. already has 1414 posts.
please PM me with your price for the job.

I am not looking for the best quality right now, so the job will go for the lowest offer.
thank you.
