Google Ads expert for home service industries

I have a small web design and SEO agency that works with small local businesses in the home services industries: plumbing, tree service, house cleaning, concrete contractors, home builders, dentists, etc. I create simple call ads on Google to generate new leads, to call my website or submit a form inquiry. I'm looking for a Google ads specialist who can help create ad campaigns, and understand how to optimize them, lower my CPC etc. Potential for ongoing work for the right candidate.
