Phone Number Finder Bot Development

I'm seeking a skilled developer to create a bot or lightweight software that reads from an Excel or CSV input and searches for phone numbers.

Key Features:
- Read data from Excel/CSV (names, usernames).
- Search for phone numbers on websites, social networks (Facebook, Instagram), and directories.
- Export results to a clean Excel/CSV file.
- Reliability, accuracy, and user-friendliness are crucial.
- Bonus: Support bulk processing for multiple entries at once.
- Support Hebrew for both input and output.

Ideal Skills & Experience:
- Proficiency in bot development and data scraping.
- Experience with Excel/CSV manipulation.
- Familiarity with social media APIs, especially Facebook and Instagram.
- Multilingual support integration is a plus.
- Strong attention to detail for accuracy and reliability.

Timeline is flexible, but I expect a polished and accessible final product. Please provide a detailed proposal outlining your approach and experience.
