Data Researcher Needed — Find Personal Cell Phones for ~200 Small Business Owners (US/Canada)

I'm the founder of a SaaS platform serving indoor golf venues in the US and Canada. I have a list of ~200 venues with the owner's name, email, and business phone number — but the business phone routes to the venue's front desk, not the owner directly. I need to reach owners directly for sales outreach, so I'm looking for someone experienced in contact enrichment to research and find their personal cell phone numbers. Data you'll receive: A Google Sheet with ~200 rows containing for each business: Owner first + last name Company name + website City / State / Country Email address Business phone number Source URL where the data was originally scraped from here is the list: https://docs.google.com/spreadsheets/d/1y65EauwYK_JhmXleBNFKKg9shgjFlOl8V6iaFseEzvs/edit?gid=0#gid=0 Your deliverable: Same spreadsheet, with two new columns added: Owner Personal Cell Phone — verified mobile number (not landline, not business line) Source — how you verified (e.g. "LinkedIn Sales Nav," "Apollo," "Spokeo," etc.) For owners where you can't find a verified cell, mark the cell NOT FOUND — don't leave blank. I need to see what you researched. Quality requirements: Verified, not guessed. Numbers should be confirmed against 2 independent sources OR from a paid lookup tool with 75%+ confidence score Mobile/cell only — no landlines, no business lines Do NOT contact the numbers. This is a research task only. I'll handle all outreach myself.
