Webscraper to find companies hiring for various positions in Uk

I am looking for a webscraper that can find companies hiring for various executive and management positions in the UK. I need a list of at least a thousand numbers to call, so phone numbers, emails are secondary. I don't have a preference for the type of companies that it finds, and I'm not targeting specific locations. These companies must have jobs going in executive and management. The companies should preferably be 100-7000 employees, no larger. The webscraper should be able to extract relevant information, such as the company names, job positions, and contact information (phone number). The results of the webscraping should be presented in a usable format such as a Google spreadsheet.
