Upwork (CRM cleanup and data hygiene jobs from businesses migrating systems), Fiverr (data cleaning and list building gigs), LinkedIn (pitch sales managers whose CRM data is likely stale after 6+ months of use).
Companies switching CRMs or launching email campaigns discover their contact database is a mess — duplicates, missing fields, outdated job titles, bounced emails. You clean and standardize the data: merge duplicates, fill in missing fields via LinkedIn research, remove bounced addresses, and format everything consistently. Charge $15-25/hour or per 1,000 records cleaned.
🚀 First Step
Create a messy sample spreadsheet with 50 contacts (duplicates, missing emails, bad formatting), then clean it to perfection as your portfolio sample.
  • Use Excel's 'Remove Duplicates' and conditional formatting for blank cells to speed up the initial audit — then manually verify edge cases.
  • Standardize every field: job titles to Title Case, phone numbers to (555) 123-4567, company names consistently — consistency IS the product here.
  • Deliver a one-page 'data health report' summarizing before vs. after stats (duplicates removed, blanks filled, records archived) as proof of work.
