Meta Business Manager Cleanup & Multi-Business Structure Setup

I need an experienced Meta Business Manager specialist to reorganize my entire account structure.
Right now, I have several businesses mixed inside my personal profile, and the assets, permissions, and accounts are not properly separated.

I need a complete cleanup and restructuring. Tasks include:

Create separate Business Managers for each business.

Transfer assets (Pages, Instagram accounts, Ad Accounts, WhatsApp numbers) to the correct Business Manager.

Fix permissions and roles, removing personal ownership and assigning proper admin access.

Standardize the structure: naming conventions, asset distribution, users, and partners.

Configure security settings, including 2FA, business verification, and proper admin levels.

Leave everything organized, secure, and ready for my team (community managers, marketing, etc.).

Requirements:

Strong experience working with Meta Business Manager / Business Suite.

Proven experience fixing complex or messy BM setups.

Ability to migrate assets without losing history.

Knowledge of Pages, Ad Accounts, Pixels, Instagram connections, and WhatsApp Business.
