Hi,
I read your all project's description very carefully, I am expert on web-scraping, I can complete your project 100% perfectly..
I can give you perfect emails(250,000) on blog-owner + which is on their website, you will get all valid emails, and no duplicate email will be present.
But it will take time to scrape valid email, si I need time.
Please check my past completed projects they all are on scraping/BOT, link is >>>> https://www.freelancer.com/u/developerphp2007.html ..
I can sure you, If you will get anything wrong from me then you don't need to pay me money, so I can sure you will get 100% perfect emails..
If you have questions please ask me..
Thanks,
Kuntal..
