Actually question is incomplete. Please draft question again so that we can assist you better

I think strategically rather than tactically, so you're asking the wrong question entirely. The fact that you're presenting your background as 'I did HR AND client relations' tells me you're stuck in job-description thinking, instead of value-proposition thinking.

Stop asking if companies need your exact experience combination.

Start asking: what expensive problems do you as a company have that someone with my weird skill mix could solve differently than pure HR people or pure client relations people?

Your power isn't in fitting into existing boxes. It's in creating a new category that didn't exist before you.

Good luck!
