Hey
I am doing a similar project to extract informations from linkedin ( companies with their industries, CEO, CEO, revenue, website urls, headquarters etc etc.)
I have 3-4 years experience in data extraction, web searching, data mining. And have a team of 10-12 employees. We can extract 1000- 1500 companies per day. And i gurantee for the quality. The quality of work will be very good.
Below attaching a sample link of that project, you can check it.
