Descriptive Data Analysis Needed

I have several data sources—Excel spreadsheets, relational databases, and a few live APIs—that need a concise descriptive analysis.

My goal is to understand:
• Trends over time
• Any obvious anomalies
• A clear demographics breakdown

Because this is an initial, low-budget engagement, I only need a basic yet reliable snapshot of each insight area: clean the data, run the core descriptive statistics, and present the findings in a short written summary supported by a few straightforward charts (bar, line, or pie as appropriate).

Please use whatever tools you are most comfortable with—Excel, SQL, Python (pandas, matplotlib), or similar—but make sure the final deliverables are:
1. A brief, well-structured report (PDF or DOCX).
2. The cleaned datasets and any scripts or notebooks you used so I can reproduce the results later.

If you’re comfortable synthesizing information from Excel files, databases, and APIs into a single, easy-to-read analysis, I’d love to hear how quickly you can turn around this initial snapshot.
