I am a PhD student from Australia in the discipline of international business. For my data collection, I intend to conduct an online survey among energy-related firms in six countries (Australia, USA, UK, India, China and Sri Lanka). For this, I need to contact managers in production, technology, R&D, and manufacturing divisions of the companies.
Based on my research model the minimum sample size is 356. Considering a low response rate (approximately 10%), I have to contact approximately three thousand firms. So far I am trying to collect this data by accessing specific firm’s websites. This is very time consuming, and in nearly 99% of cases, I could not find the specific email address I am looking for.
My question is with respect to the availability and ability to find these firms and specific contact persons contact details. Are there any websites or firms who could find the specific firms, contact persons (managers in production, etc.) and their specific email addresses?
