Manual contact research, 8,000 verified US theater program contacts

We need 8,000 verified, deliverable email contacts at theater programs across the United States. This is hand-researched work with a source URL for every contact, not a purchased list or a database export. Budget: $880 fixed price, billed in four tranches of 2,000 contacts at $220 each. You're approved for the next tranche only after I've reviewed the previous file. If a tranche doesn't meet the standard, we stop and nothing further is owed. All four to be completed as soon as possible. (please provide expected timeline) Segments and mix: - Community and local theaters (secular): 30% - K-12 school theater programs: 28% - University and college theater programs: 20% - Professional and regional theater companies: 15% - Youth and children's theater companies: 7% Sequencing: K-12 first, since that buying window is time-sensitive. Community and youth next. Professional and regional after. Universities last. Requirements per contact: - First name, last name, title, institution, city, state, email - A live source URL showing where the contact was found - A short evidence note describing what that source says (for example: staff directory lists this person as Theatre Director with this email) - Segment label - No blank fields in any of the above Who qualifies: - The person who directs, produces, or runs the theater program or music theater productions - At K-12 schools, that's typically the drama teacher, theater director, or program director - Not technical directors, band directors, or choir directors (these titles may help with plays or musicals but are not the core buyers at schools) - No generic role-based addresses (info@, office@, boxoffice@) unless flagged separately Contacts per organization: - Strictly 1 to 3 people per organization, never more because an organization only buys one license. - If an institution lists many qualifying staff, pick the 1 to 3 with the most direct responsibility for running productions - Padding an organization with additional names to reach volume is not acceptable, and those rows will not be counted toward the total Deduplication against existing list: -We will provide a file of contacts already sourced, roughly 2,000 verified contacts plus several thousand additional names already researched at organizations already covered -Every delivered contact must be checked against that file before submission. Duplicate email addresses will not be counted or paid for -Organizations already at their 1 to 3 contact limit in the existing file are considered complete. Do not return additional people from those organizations -Each tranche file must include a column confirming the contact was checked against the provided exclusion list Verification: - Every delivered contact MUST return "good" or "ok" from a verification service (NeverBounce, ZeroBounce, or MillionVerifier, your choice) - Catch-all and unknown domains don't count toward the total; deliver them on a separate tab if useful, but they aren't billable - Invalid addresses don't count Geography and exclusions: - United States only - No churches or camps unless it is clear they produce 3 or more musicals or plays per year Please apply only if you've done hand-researched contact sourcing with source citation before, and tell me realistically how many contacts per week you can deliver at this standard. We'd rather have an accurate estimate than an optimistic one.
