Google Ads Correction & Optimization for Reiki in Canada

I need an experienced digital marketer specialized in Google Ads to diagnose why my ads are being denied and help correct them so they can reach the first page of Google again. My ads used to appear on the first page for searches related to 'Reiki' in Canada, but they are no longer showing. This initial work should take just a few hours, and I am starting with a budget of 150 CAD. Based on the results, there may be further work to discuss.
