Connect Facebook Profile to Business Page - single task

I need assistance with a one-time task to connect my existing Facebook profile with my business page. Both the profile and the business page are already set up, and I have administrative access to both. The goal is to ensure seamless integration between the two, allowing for efficient management and enhanced visibility. In addition I need another profile to be deleted without the other profile being affected by it. Both the profiles are currently registered with the same account. I need someone who knows 100% what s/he is doing so no data get lost. It would be optimal if the profile could get into professional mode as well. A German speaking person would be ideal, since the account runs in German. You could switch up the language settings for the duration of the task.

Key Requirements:
- Connect an existing Facebook profile to a business page
- Ensure proper integration for effective management
- Maintain administrative access and control over both accounts
- Delete one of the two profiles without any issues
- Put Facebook profile in professional mode

Ideal Skills and Experience:
- Experience with Facebook page management and integration
- Familiarity with Facebook's administrative tools and settings
- Strong understanding of social media management best practices

If you have the expertise to help with this task, I look forward to your assistance!
