I will do data mining, web scraping, data extraction, data harvesting, data crawling, call it what you want, I can even build custom scraper and give it to you, so you can scrape and update later by yourself.
I can mine, extract, scrape the data from mostly any website, mobile app, software, database file, I'll have to check first so contact me before ordering.
I can also extract, scrape, mine data from PDF if they are structured enough.
I can output in different format: CSV Excel sheet, TXT, XML, JSON, SQL.
I developed my own extraction / scraping framework, using Python, python-requests and python-lxml.
My Scrapers, Data miner, crawler.. uses proxies to keep you anonymous from the website to extract, it also uses multi-threading, which make it really fast, up to hundreds of queries per second if the website's server is performant.
I can compile custom scrapers for Windows (.exe) or Mac OSX, I can also give the Python source code for Linux users...
I will keep revising the scraper or data until you're happy about my job
