Looking for a Google Looker Studio (aka Data Studio) specialist

We need someone highly skilled with Google Data Studio (New version is Looker Studio) to build custom dashboards using GA4 and GA3 datas.

Enventually, we would combine other datas but for the moment, just datas from GA3 and GA4.

Please, dont bid on this project if you are not really skilled with Looker Studio.

Thank you
