I have a clean CSV with roughly 2,400 Swiss staffing companies (name, address and phone are already there). Your job is to add three new columns for each record: • company website domain • the owner / CEO / Geschäftsführer’s full name • that person’s direct email address I expect the final file back in the identical order and layout, simply extended with the new data. To keep look-ups consistent you can lean on online databases such as Apollo—this is the method that has brought me solid results so far—but you may blend in LinkedIn, Google Maps, manual verification, Hunter, Skrapp or similar tools if it helps you reach higher accuracy. What matters most to me is trustworthy data: bounced emails or wrong decision-makers are far more painful than an incomplete line. When you reply, focus on the experience you have with projects of this kind and the accuracy rates you normally achieve for small Swiss or other regional companies. A short note on your workflow and expected coverage percentage is enough; no need for a long proposal deck. Deliverable acceptance • The CSV opens without formatting issues. • At least one verified email per company where a domain exists. • Spot-checks (I’ll review 10 %) show <3 % hard-bounce rate. • Titles match the seniority requested (owner / CEO / Geschäftsführer). If this sounds straightforward to you, let’s lock in a fixed price for the whole 2,400-row file and get started.
