Happy to help if you want to send me a message. My details are at: www.drivedigital.net.au/shopify/
Let me know your website URL too.
Fahed, perhaps try to send some ads that suit better a cold audience first. I mean, we are not on Facebook in "buy" mode but more in a "relax" mode. Try to craft ads that redirects users to a low friction landing page and ask them for their email adresses. After that you can do some remarketing via custom audiences.
