You can use our service, 80legs, and start crawling for this information right away.
80legs is a web-crawling service that is easily customized to meet your specific needs. You need little to no programming experience to extract the information you want.
If you only need to crawl fewer than 100,000 pages or want to try it out, the service is completely free. We offer more feature-rich subscriptions at $99/month and $299/month after that.
