Google Tag Manager Setup Expert

I recently decided it’s time to organise my tracking properly and move everything into Google Tag Manager and Google Analytics 4 propertys. Right now I have many containers and GA4 accounts, so I need someone who can configure them the right way

Here is what I expect:

• GTM containers built to best practice, published and linked to my site.
• GA4 property correctly mapped and connected to the containers, with basic and custom events firing exactly where they should.
• Clear, human-readable naming conventions so any future edits are straightforward.
• A short hand-over document (or Loom video) showing me where everything lives and how to verify that the data is coming through.
