Refine GA4 & GTM Conversion Tracking

I am looking for an experienced Google Analytics 4 (GA4) and Google Tag Manager (GTM) specialist to properly configure event tracking on my website.

Google Tag Manager is already installed and working.
All website forms redirect to a thank-you page after submission.
The task is to configure tags, triggers, and events, not to install GTM.
