From one already structured CSV or workbook table of up to 5,000 rows and 15 columns, I produce a one-page summary with up to three defined metrics and two charts. We agree the metric definitions first; messy source data or multiple sources need a custom quote.
I preserve the original, check calculations against the source, and provide the report plus its underlying table. One revision within scope is included. Delivery is within a week after receiving the data and agreed definitions. Tell me the decision the report should support. Please keep private data out of the first message.
