Chronicling Witness Accounts

For historical purposes, I would like to chronicle witness accounts of a shooting done almost fifty years ago. Over 100 people witnessed the crime and I have their written testimonies, both first person testimonies and third person testimonies. I would like to chronicle their testimonies seconds before the shooting, during the shooting, and seconds after the shooting with different sources providing a different color coding to the chronicle you will type or cut and paste. After I show you how to research on the internet and chronicle the testimonies, you can give me an idea how much you will charge to do the job. You can look at the attached file which will give an outline (and two examples) of what I am looking for including how I would like you to color the text. I imagine over 100 testimonies will be analyzed and put in the format that I need. As you investigate the project, it will become apparent what the scope of it will be for you and how much you feel you should get paid.
