Hire a content writer or content marketer?

Hey guys, I have a Chrome extension that has a pretty decent retention rate and now has about $1k MRR. I want to start doing some marketing for this, and I was thinking it would make the most sense to do content marketing. One of the things I definitely want to do is blogging. I would like to hire someone to help me on this side of things. But would it make more sense to hire more of a generalist like a content marketer or something more specific like a content writer? Thanks.
