Content for backlinks

In my company, I have a target of creating 200 backlinks in a month. However, there is only one person as a content writer. She is busy writing on-page blogs, guest posting blogs, and web stories. She doesn't have time to write off-page content. I need content for 40 Q&A submissions and 40 blog submissions. I don't know how to manage the content. Please help me with what I should do.
