Web Email Scraper

I'm looking for a program that can search the web and return email addresses based on certain keywords and industry-specific terms. The program should be able to run whenever I prompt it and return the results in an Excel spreadsheet.

Ideal candidates for this project should:
- Have experience in web scraping and email extraction
- Be proficient in programming for creating such a tool
- Understand how to filter results based on specific keywords and industry terms.
