Enriching Contact Info for Companies Using Limited Data

Hey Clay team, I have a list of companies with their name, website, industry, etc etc. as well as the primary contact name for these companies. We used an agent to scrape PDFs that these companies have published online for the primary contact. Their name is the only data we have. How can I enrich contact info (email, social profile, etc.) with the data I have? Struggling to use the "Find Contacts" option right now
