I’m building a clean, reliable reference for the GDP indicator and need a freelancer who can source, verify, and deliver that data on a quarterly basis. The task is limited to GDP only—no other economic metrics—so your focus will be on finding authoritative releases (e.g., World Bank, IMF, national statistical offices), capturing each new figure as it is published, and keeping the dataset consistent over time. Deliverables should be: • An initial spreadsheet (Excel or CSV) containing the latest available quarterly GDP values, clearly time-stamped and cited. • A short note on data provenance for every entry (URL or document reference). • An update routine I can run or a brief guide describing exactly how you’ll refresh the file each quarter. Accuracy and source transparency are the acceptance criteria. If you already have scripts in Python, R, or prefer a manual method, let me know; I’m flexible on tools so long as the final data remain verifiable and neatly formatted.
