"General Black Accent Coach" Needed For Up And Coming Actor/Entertainer

Looking for an accent coach that knows how to teach a general natural sounding African American Accent via video chat for lessons. I am looking to acquire the accent for upcoming roles as an actor and also personally in my social life meaning you will have to know how to teach all the phonetics, nuances, delivery, flow patterns etc. By "general" African American meaning not really trying to have a Southern African American accent or a New York African American voice but a general one I.E. Kanye West, Will Smith, Jaime Foxx, Kevin Hart, Michael B. Jordan etc... Hourly rates will be discussed during first meeting over video chat. Also would like to see some sample work if possible. If everything is good we will come up with a weekly schedule. I understand it's more about learning a new dialect from a specific region but I have to put it in broad terms for you to understand. If you feel you can provide this service, please reach out to me. Please serious Inquiries only.
