i want to do it with secondary data instead of primary. i would really appreciate help

What is the research question you are trying to answer? I think it is a bad idea to choose your topics and methodologies before deciding what you want to answer. You have done lots of reading, so think what do you not know that you want to know? Or start with a hypothesis and try to prove/disprove it. I hope that helps you get started.
