What to send

  • Targets, region, filters and desired number of records
  • Required fields and an example row or schema
  • Permitted sources and fields that require verification

Start by describing the materials you already have; missing details can be added when we agree the scope. Before work begins, we will confirm the materials, permissions and working conditions needed for your specific task.

Possible outputs

  • CSV or spreadsheet with the agreed columns
  • Source URLs, check date and confidence or verification status
  • Notes on missing records, duplicates and inaccessible sources

Key check

Each row must be traceable; missing fields and unverified states must be marked.

Verifiable acceptance · 3
  • Fields and missingness are transparent
  • Sampled source pages support the extracted fields
  • Duplicates are resolved using an agreed rule

Hypothetical brief & output structure

Illustration · hypothetical

    Self-directed AI product

    Workflow and product practice, not evidence of market success or client delivery.

Self-directed work and published projects demonstrate relevant practice. They are not paid-client delivery records or guarantees for this task.

Start with a short note

Three answers are enough. I will reply with what else is needed and whether a diagnosis comes first. You get a quote before any work starts.
