Enhanced Conversions & GA4 Setup

I need a specialist who can wire up my existing CallRail implementation so every phone call and form submission on three custom-coded landing pages is reported as both a Google Ads enhanced conversion and a GA4 event. The site is built using base44 ai agent consudting of .jsx/css/html and can easily integrate with any platform — everything should run through Google Tag Manager and API.

What I want done
• Build or refine a GTM container that fires on phone calls and form fills captured by CallRail.
• Zapier workflow for new callers, repeat callers, good_leads, tagged calls as qualified/converted.
• callrail fotmfills is integrated into lead docket using webhooks.we also would like to share lead docket updates back to callrail or Google ads for a full ROI spend for cases/clients signed up.
• Pass the required hashed user data to Google Ads so the same interactions show up as enhanced conversions.
• Mirror those same triggers in GA4, marking them as conversions there as well.
• Validate the implementation with Tag Assistant, the Google Ads diagnostics panel, and real-time GA4.

Acceptance
The job is complete when test calls and submissions populate in both GA4 and Google Ads with the enhanced-conversion flag and no console or GTM errors appear.
