Devil Barnett GEN

I am promoting my detective novels to the media industry and I need about 3 different audiences of FB influencers. and lookalike audeinces. I have a FB business page, but since I am not a tech person i am having lots of trouble navigating and setting up my FB ad for various countries and my target audiences and my look alike audience. Whenever I try i am always navigating away from the page and things keep going wrong, so it is easier if I get someone who knows technically how to do it. I tell them what I want and they can execute it.
