Looking for someone who can help build the persona, and then actually find those people in media online
Have you completed this project yet?
I am holding a 12 week course teaching students how to complete this whole process from research to execution of the Campaigns.
I'm assuming you have started already.
However, if you need someone whose core competency is creative targeting and demographic/psychographic research for the purposes of executing Online Marketing Campaigns; I am your gal!
