Need someone to gather information on leads for Excel sheet from the internet

I have a spreadsheet of 600 investment advisor leads from my city. 400 of them are missing emails. Some are missing phone numbers. Around 30 have changed firms. I need someone to search up their names on the internet, find their websites (investment advisors have websites), and update all the information on the document so that it is accurate.

I also need you to double-check all existing lead contact information.

Need English fluency and 100% data accuracy!

NEED NDA
