Google Analytics Expert

Hi there, i run an analytics agency and I need some help with GA work for my clients.

This would be GA4, Google Tag Manager work. The standard jobs that we take are:
1. Audit a GA4 account, find inaccuracies
2. set up ga4 from scratch
3 track some events and pass them to Facebook or GAds pixels

Nice to have experience:
Setting up a data layer
Firebase SDK
Server-side tracking
