History Coursework Watch

I have a coursework assignment to complete that's worth 20% of my final grade in A2 History for AQA exam board. The topic that I have chosen to study is the Crusades. The question is to do with if the crusaders from the western Europe were motivated due to religious devotion 'setting out to Jerusalem or Outremer', covering from the First Crusade to Fourth Crusade. I am asked to prepare a detailed plan for it due next week. I know my basic stuff for the topic but what can I include in my plan that's going to be very useful and will perhaps allow me to achieve a top grade for this coursework. Any useful suggestions would be appreciated. I did my interpretations and contemporary source analysis and the word limit for this particular coursework is 3500 words covering at least 80-120 years of content.
