Company Merger inc. google workspaces + ads, re-directs etc

Hello, I'm looking for someone who can hopefully carry out all the below:

I have two companies:
ENCAPS - a service company installation of shrink wrap - www.encaps.co.uk
Ecoshrink - A material sales business wholesaler of shrink wrap products - www.ecoshrink.co.uk

I am re-naming ENCAPS to Ecoshrink Installations Ltd

This is so I can unify the logo to improve brand strength, and simplify marketing efforts.

I need help to:

Unify both accounts into one Google admin console, with all email addresses switched over with aliases. I need robust catchalls / re-directs from old to new.

I need all 301 re-directs set up so all ENCAPS traffic in directed to the new Ecoshrink website

The google Adwords would need unifying also, with all old branding removed, or duplicating the current campaign with the updates in mind.

I also need help with making sure the google business profile / reviews remain intact, and the best way to go about this.

Plus anything else I probably might have not thought of.
