Looking for advice: I have a client project that requires building a large, ethical, and compliant dataset of up to 10M Indian IT professional records. Deliverables are CSV batches of 100k profiles each. Priority fields: email, phone, full name, job title, employer, location, profile URL.Other optional fields: education, skills, headline/summary, photo, provenance metadata. Important: No scraping that violates TOS, no bypassing, no private data. Only public/consented data, ideally from vendors, partners, or opt-in sources. Has anyone here successfully done something at this scale (10M+)? - What vendors, integrations, or strategies worked best for you? - Any recommended verification pipelines for email/phone at this volume? Appreciate any pointers.
