I need comprehensive contact data pulled directly from publicly available company websites. The task is straightforward: harvest every email address, phone number, physical mailing address, owner’s name, and the site’s URL you can reliably locate on each target domain. I’m fine with whatever stack you prefer—Python with BeautifulSoup, Scrapy, Selenium, or a headless browser workflow—as long as the scraper respects robots.txt where required and avoids rate-limit bans. Deliverables (CSV or XLSX, one row per company): • Company URL • Owner / principal name (if visible) • Email address • Phone number • Mailing / registered address Acceptance criteria: the file must contain only verified, non-duplicate records and include at least one contact channel (email, phone, or address) for every listed company. A short README explaining how to rerun or extend the scraper rounds out the job.
