Automating Google Maps Searches for 1000 Companies: Need Help!

Dear all, I am trying to use the google maps search template for 1000 companies with, on average, 500 location. Can someone help me predict the cost? Can I automate the 1000 searches -- so far I only figured out how to do it for one company but I would need to manually execute it on 1000? Or is there are feature where it loops through? At the end I would love to have a panel data set.
