Teach Me How to Use Mail Chimp

Teach me how to use mail chimp. I plan to rent some lists of email addresses. I want to know how to import these lists into Mail Chimp and keep them separate. I want to do different email campaigns to different lists. I prefer to learn through Zoom sessions where you would be able to show me your computer screen in detail, show me the buttons to push or Mail Champ features to access. I would like the Zoom calls recorded and sent to me. I would prefer to hire someone on PST because I am on the West Coast and sometimes I have to work in the evening. I do not have very much computer expertise. I know how to do basic things on a computer, use Word and PowerPoint but that is about it. I need a patient teacher.
