I'll done a lot of transparent scraping for myself and other companies, using node.js and a browser driver called Selenium. For heavily spam protected sites like Soundcloud, this is a necessity.
Relevant Skills and Experience
I lately scraped over 80 000 company emails and websites, from Swedish company listings together with website quality params. I can deliver this for $50 within 3 days, with zero bounce rate.
Proposed Milestones
$50 USD - Deliver scraper together with 200 000 emails with said parameters.
Stay tuned, I'm is still working on this proposal.
