Google Ads and Analytics Firebase for App conversion setup IOS and android -- 2

We have IOS and ANDROID apps and have a website + Apps running on google Ads.

Looking for expert who can setup all the detailed tracking, conversions goals for website and Apps for google ads.

Remarketing is collected on website and remarketing targeting with the App install, so need all the tags, conversions working properly.

I prefer to do it online together, setting up all the tags, goals etc.

Have to be an expert with GA4, Google ads conversions, Firebase, App tracking IOS and ANDROID, Google remarketing cross platforms etc.
