Any tips on where to find a Virtual Assistant?

We're having a hard time finding a Virtual Assistant to join our team to upload designs, do some blogging, social media etcetera. Any tips on where to find qualified VA's with experience in the Graphic Design industry? I've posted a job on Upwork (https://www.upwork.com/job/with-experience-Graphic-Design-industry-Fun-job_~01ecc81145c2a1028e/) but no luck so far. Appreciate your input!
