Price reference from websites

Hello. This is for a personal project I´m just starting. This is part of a bigger project. From a list of articles in a data base or spreadsheet or text file (not defined yet), is it possible to obtain a price reference from one the following pages that could sell online that article : [login to view URL], [login to view URL] or [login to view URL] All pages are in spanish. Input would be a file (or table) with article descriptions. Output should be the file (or table) with the article descriptions + the price of the article (taken from one of the sites) + name of the site. Articles will be like the ones on hardware stores. Output needs to be stored and displayed on website eventually. Source code and method needs to be handed in. First project milestone: do a test with list provided by myself. Second project milestone: tune the scraping to take into consideration typos or articles with similar descriptions, example: article description in mm vrs article description in inches or articles with different names that mean the same thing. Other considerations could rise in order to obtain an adequate result. Will work and pay by milestones. Any comments of considerations let me know.
