Mass Data Research: Verify 4,000 Exhibitors

I have 6 Google Sheets with ~4,000 company names (exhibitors across several Las Vegas trade shows). I need a fast, accurate researcher (or small team) to verify each record and fill in the missing fields.

Deliverables (per company):

Official Website (domain)

Confirmed Exhibiting? (YES / NO) — link to exhibitor page or proof URL

One valid email (generic like info@, sales@, marketing@ OR a decision-maker incl. job title email if publicly available)

Source (exact URL where you confirmed the exhibitor / email)

Notes (if no email or site found)

Must-haves / Rules

Use only public official sources (show exhibitor directories, company websites, LinkedIn). No scraping private databases.

Accuracy is required — if you can’t verify, mark the row and explain why.

Do not submit random Gmail/Yahoo personal addresses.

No AI-generated work. This is manual web research.

I will provide the Google Sheet after hire.

Timeline & Payment

Fixed price: $50 total

Deadline: deliver completed sheet within 48 hours of hire.

You may work with a verified small team but outcome must be clean and coherent.

To apply

Provide 3 sample rows (website + email + source URL) from any show to verify quality.

Confirm you can deliver full 4,000 rows for $50 within 48 hours.

State if you will work alone or with a team.
