Data scraping of printing website - need complete list of prices for all available quantities and options

I am looking for a Freelancer to data scrape an Australian printing website, in order to obtain a COMPREHENSIVE list of prices they offer for every product, for every quantity, for every available product option. The web address of the live site will only be provided to short-listed Freelancers, however for the purposes of quoting and to see if your skills are adequate, the live site is similar to: [login to view URL] (look at the list of products under the "Printing" menu) with the only difference being the live site will be behind a user login (I will provide the username and password). I need the data to be provided in an Excel spreadsheet. I also need the scraper to be setup as a product that I can own so that I can run it on a weekly basis or as and when I want. In addition, I have multiple user ids for the live website so the product you provide must be able to take inputs via some method for username and password. To reiterate, I need the price for every product, from every category, with every available option, with every available quantity, scraped and provided in an Excel spreadsheet. And I need to be able to repeat the data scraping every week or whenever I want so it needs to be provided in a form/script that I can take and own. Thanks and happy bidding! A
