Verified Email Addresses for Medical and Dental Professionals

I have a list of medical and dental professionals (members of the Christian Medical and Dental Association) and need verified email addresses for each one — both their personal/direct work email and their office/practice email where available. What I'll provide (spreadsheet): First Name, Last Name, Credentials, Specialty, Practice Type, Company, Street Address, City, State, County What I need back: The same spreadsheet with two added columns: Email and Office Email. Email addresses only — no phone numbers or other data needed. Important — this is the key requirement: I've already tried RocketReach and Seamless.ai and could NOT find most of these contacts. You'll need access to specialized medical/healthcare databases or provider directories (e.g., NPI-based tools, Definitive Healthcare, medical practice directories, state licensing boards, or similar) to source and verify these. Please tell me in your proposal which databases/tools you'll use — I won't consider bids that just say "I'll use LinkedIn/Apollo/Seamless." Requirements: Verified emails only (please run them through a verification tool like NeverBounce/ZeroBounce — no guessed/pattern emails unless verified) Note in a status column whether each email is Verified, Catch-all, or Not Found Accuracy matters more than speed To apply, please tell me: 1. Which medical databases/tools you have access to 2. Your expected hit rate on a list like this 3. Price (flat per record or total) and turnaround time Optional: complete 5 sample rows (I'll send them) to show quality before we start
