Hi, I am a new freelancer, but also a web scraping expert. I've ever implemented a web scraper in C++ language. Therefore it wouldn't be difficult for me to do this project for you. If you want some sample, just PM me and I will show you that I am very skillful and capable to get this work done. Also, if you're afraid of awarding me the project, given that I am a new freelancer, I could make, as a sample, a web scraper which would extract some information from a web site that you would specify.
As for the implementation, I would make the Web Scraper in C++ language with the Qt framework which is cross-platform. That means I could compile an executable file for Windows, Linux, or even Mac OS. Besides, the output format could be CSV as you mentioned.
