I need a complete audit of my Google Ads and GMB accounts. My contacts stopped

I have been running my Google Ads campaigns for over a year now, and I'm looking for a professional audit of my accounts. I need an experienced consultant who can identify any technical issues and fix them quickly in order to optimize my campaigns and improve my ROI. My budget for Google Ads is around $2,000 per month, though I am willing to invest more if I get improved results. This audit requires someone who is experienced and knowledgeable about Google Ads, GMB accounts, and the associated technical processes.
