We would like you to build an excel file populated with all basic contact information (company name, address, phone number, email address, website, etc) for all electricians in the US.
You can build this directory by building your own web crawler/scraper or by using one of the existing web crawlers. We would like you to crawl most common directories like Google Local, Yelp, YellowPages,... as well as many others that we are looking you to suggest us...
The most important piece of data are the phone number and the email address. As such we would like you to find all those businesses that have a website (and hopefully a phone number and email contact on the website).
The time is of essence in this project as well as accuracy of data. Please respond with the methods you would use and the details of a similar project that you have completed in the past.
