Find company domains from Google and put into Google Sheets

I need somebody to help turn a large number of company names into a list of company domains (ie. websites). The process is simple: Open Google Sheets Copy the first company name Paste into google and search. Copy the CORRECT domain and paste it in the column next to the company name in Sheets. I am aware this process can be automated, however, the results aren't accurate, and I have found the process of checking takes almost as long as doing it manually. If somebody has a way to accurately scrape this data & ensure 100% accuracy, I am happy for it to be done this way. Also: the advantage of having a human help with this is that they can use some intelligence and intuition. E.g. I will give you a list of 5000 Marketing Agency names. Some of them will turn out to be obviously wrong (eg. you see Coca Cola in the list). These obviously wrong lines can be left blank. Another example is the company name may say 'freelancer'. This is obviously wrong, so again, it should be left blank.
