I'm researching in an "Natural Languague Processing" project in my university. I have to set up many crawler to scrape data(include: info about product and comments from customer and anything else) from Facebook pages, online shop and news website. I think I can complete your project with my experiences not only on web scrape but also on other technologies.
I use Python with Scrapy Toolkit, and Python + Graph API on facebook.
Here is my email: khanhnv3007@gmail, and my skype ID: khanhnv3007. I'm looking forward to discuss further details with you. I think I can help and really want to help you.
Thank you.
