Scrapping program

I'm looking for a talented freelancer to create a program that will create a scrapping program to run from a website of my choosing. I have a specific data set in mind that I need retrieved for research purposes. This project requires knowledgeable experience in dealing with data scraping and should be familiar with the best practices. The end result should be a tool or a framework that provides the required data from the requested website in an efficient and timely manner. Expertise in setting up parallel tasks to speed up the process is a plus. Good communication skills are very much appreciated as I will require regular updates on the progress. Full requirements and specifications will be provided to the selected freelancer.
