MS365 Expert

We have 3 separate companies all coming together in a Group. Some are still using Google Docs. Others are using MS365. We want to migrate that into MS365. Then train everyone. Plus identify some functions which can be automated via MS365. Not sure yet what MS365 is capable of. We use Teams and Planner but there are so many apps we could use. I want a webinar platform, repository for video assets and a payment gateway. Surely MS365 has that! Plus much more. By the way, I am the Group CEO and I am posting this because the team is a bit fragmented and busy at the moment. I am looking for a trusted partner to help us on the journey.
