How To Hire a True SMM Expert?

I am really tired of dealing with "regular" SMM companies that only know how to post glitzy pictures and talk about "branding" …

I am looking for someone who knows how true cost effective BH or Grey Hat SM marketing works.

Please recommend me someone. We have products in hot & trending niches and need someone who could help us manage our decent SM budget and make a killing in FB and IG.
