Gmail Cleanup, Consolidation & Single-Inbox Setup

I'm looking for someone experienced with Gmail/Google Workspace to help me simplify and organize multiple Gmail accounts I've created over the years. I own a primary LLC along with two rental property LLCs. To stay organized, I created separate Gmail accounts for various purposes, but managing multiple accounts has become cumbersome. Some of the accounts are actively used, while others were created in error, duplicated, or simply no longer need an email presence. What I Need Help With * Review all existing Gmail accounts * Inventory and document what each account is used for * Identify accounts that should remain active * Identify accounts that can be retired or deleted * Migrate any important emails, contacts, or files from accounts being closed * Safely delete unnecessary accounts * Recommend a cleaner and more manageable email structure going forward Main Goal I'd like to manage the remaining accounts from a single inbox whenever possible. I'm looking for someone who can: * Set up one central inbox for managing email * Allow me to send outgoing emails from the appropriate business/account * Maintain separate identities for my LLC and rental property businesses * Reduce or eliminate the need to switch between multiple Gmail logins * Recommend the most efficient long-term solution Ideal Experience * Gmail administration * Google Workspace * Email account consolidation and migration * Gmail forwarding, aliases, and "Send Mail As" configuration * Small business email organization * Google account deletion and cleanup processes When Applying Please include: 1. Examples of similar Gmail cleanup or consolidation projects. 2. Your recommended approach for managing multiple Gmail accounts from a single inbox. 3. Whether you would recommend Gmail forwarding, aliases, Google Workspace, delegated access, or another solution. 4. Your estimated cost and timeline. Additional Context This is a personal/small-business project, not a corporate environment. The goal is to reduce complexity, eliminate unnecessary Gmail accounts, preserve any important information, and create a simple, long-term email system that is easy to manage. **Bonus:** If you can recommend a structure that reduces the number of email accounts I need to maintain while still keeping my businesses and rental properties organized, I'd love to hear your suggestions. .
