I'm familiar with this type of work, recovering deleted files, and so on. The 12 questions are mostly straightforward.
Am I right to assume that on each image are a number of deleted files? Sleuthkit would be used to analyze the filesystems, and determine information about the activity on the drive including deleted files, folders, groups, etc
I'll charge the $25 to do the actual analysis with sleuthkit, and send you the results, organized neatly. The deliverable from me to you would be a text file with written answers, and a folder of screenshots labelled by question number. Sorry but I would need to charge more to make a professional looking PDF report. But anyone can do that, so for now, I suggest we dig into these images with sleuthkit and gather our analysis results!
I'm open to discuss this further, but it seems clear what needs to be done from the 12 questions. Thanks.
