Set Up ReTargeting Data Sources in Google Ads & Facebook Ads

I have a successful existing video campaign running for the past 3 months in both Google Ads (Youtube Video campaign + Google Adwords), and also running in parallel on Facebook Ads.

I need specific assistance to configure the data sources on Google Ads to allow re-targeting of this same video campaign (and a parallel Adwords website-based campaign).

Specifically I need help to set up google data sources and targeted audiences, those sources being
- users who have viewed or engaged with the existing YouTube video campaign in the past 3 months
- visitors to our Wordpress / element or website using google tags / pixel / cookies or similar
- users who have viewed or engaged with our Facebook ads campaign
- existing users
- customers that have signed up to our email campaign (eg source is an email contact list hosted on SendInBlue, connected to Zapier)
- Engaged followers or visitors to our existing social media pages (Instagram and Facebook)

Additionally I want to use my existing google ads video campaign (eg those who viewed or engaged with that campaign in the last 3 months) as a data source to retarget these same customers via a Facebook Ads Video campaign.

I am familiar with Facebook Ads, use of Facebook Pixel, and have run successful campaigns and set up retargeting audiences to function as desired.

I need help with the Google Ads interface to set up data sources and audiences, install a tracker on my Wordpress (Elementor) website, and to cross-populate existing google ads and Facebook ads data sources into each other for retargeting purposes.

The campaign is for an International Mountain Bike event - I already know my audience and customer base extremely well so have a very specific idea on who I would like to target and re-target.

To be clear, I would like you to provide a few hour's training / consultancy to show me how to set this up myself in future, via an online conference (shared screen or similar).

The video media (in "long" 180s format plus an attention-grabbing 15s format), text, and campaign material is ready to go - I just need TECHNICAL help in setting up the Google Ads platform and data sources.
