Google Tag Manager + Google Analytics

I am looking for someone who is an expert in Google Tag Manager and Google Analytics.
It is a WordPress site.

Do not bid on the project if you do not have good knowledge of this.

Want to connect the site and forms to Google Analytics.

• Create events that fire only on success URL (`output1=success`):
• form_submit_success_first → first submission in session (primary conversion, sent to GA4 + Ads)
• form_submit_success_additional → additional submissions in same session (secondary, GA4)
• form_submit_success_direct → if referrer ≠ WEBSITE (secondary, GA4) + form_submit_success_additional
• (optional) form_submit_success → catch-all event (all success)
