I remember where I did my first paid ad for a company that provided holistic healing https://www.enlightenwithingle.com/ which was quite difficult at first since I barely had the grasp of ads. I found out that the best way was through Facebook so I found keywords related to spiritual consultant. The owner was friendly since he knew it was my first time but later when I delivered quality work the owner became extremely happy. However my journey with him was only for a while since I move on to another company.
