research on Africa

I am looking for a researcher to help with a project that will provide a broad overview of the History of Democracy, the governance systems in African prior to colonization and how democracy has worked or not in Africa post colonisation. I am looking for someone who can produce a high-quality result in a week. Experience with democratic systems and Africa is highly preferred. If you have the knowledge and skills to provide a detailed and insightful overview of this, please reach out to me!
