Search for websites by company name

Question

I have a list of 6,000 company names (along with their headquarters address), and I need to find a web address for each of them. I am considering using the Google Web API (obviously, it will take several days, since only 1000 queries are allowed per day) (find "COMPANY_NAME CITY STATE"), and then do the first result. However, I am not 100% sure that this will work, and I feel that there is a better way. I can do this in any language that I really know, in C ++, Java, PHP, Python. This needs to be done only once.

How can I use WHOIS for this? I know how to do this if I already knew the URL, but not vice versa (name for the URL). And what would I do if it was registered privately?

By the way, this is a US business.

Answer 1

To do this, you can use WHOIS instead of the Google API.

Answer 2

Use Amazons Mechanical Turk . It is ideal for tasks that are difficult to automate and, as a rule, need an identity check. It will cost a little, but it should be manageable, depending on how bad you want to get results.
