Gmail to Office 365 Migration

I'm looking for an experienced IT professional to plan and execute a migration from Gmail to Office 365 for my company. Let's cover the key elements:

- We are a small company that has 5x current Gmail accounts

- Email Migration: We are currently using Gmail, and I need to migrate all mailboxes for less than 3 employees over to Office 365.

- Integration and Functionality: The candidate hadn't specified any particular functionality to retain post migration, but a comprehensive understanding of the full suite of Gmail services will be important to ensure a smooth transition and to identify any service-specific challenges in advance.

Ideal skills experience:
- Ability to attend on-site for part of the preparation prior to cut over (Rose Bay NSW 2069)
- Proven expertise in similar migrations especially Gmail to Office 365.
- A nuanced understanding of email systems, cloud services, and data migration principles.
- Excellent problem-solving skills to manage any hiccups during the transition.

Please place your bids if this is a task you can handle expertly. Estimate the timeline and outline potential issues, if any. We would prefer minimal operation disruption and a seamless transition.
