Insert google tag tracker into my shopify page

I am looking for a freelancer who can insert a Google tag tracker into my Shopify page. Specifically, I want to track product views, add to cart clicks, and checkout completions. I do not have the Google Tag Manager code set up on my Shopify page, so I need the freelancer to set it up for me. The project needs to be completed within 24 hours.

Ideal skills and experience:
- Experience with Shopify page customization
- Knowledge of Google Tag Manager and tracking codes
- Ability to work quickly and efficiently to meet the tight deadline.
