Virtual Assistant (Perfect English Writing Required)

I am looking for a long-term virtual assistant to answer my customer service emails for a health-related business and to help organize systems to make my business run more efficiently. I also need help with Social Media and content generation.
Knowledge of health (especially natural health), a high level of organization, and perfect English are necessary. If you can write health content, that would be a bonus.

I am looking to work with someone on an ongoing basis for several years ideally.

Please send samples of your writing and more information about your background to me.
