Data Entry + Picture Gathering

This job is about getting book information from amazon website and provide it in a given excel worksheet, with certain information (11 items per book in a Excel worksheet, attached). Save the first 2 pictures of the book in JPEG format: - Pics and Description files must be named with the ISBN-13 code (pics must have a and b after the ISBN-13 name, to indicate first and second pic. "A" pics must be the main book image). - Pics must have a minimal resolution of 200x200px. If you can't find it on the given website, images google usually fill this gap. Save the "Book Description" in a text format, preferably .txt. These information are given: - Titles; - Cover; - Rank; - Some Authors; - Some Prices. Authors and Prices must be completed (if missing) or updated. There are 1679 books to get information. 269 books are the same, only changing their "cover" type (paperback or hardcover), which makes the work easier (but I still need the entire line of data, changing it's dimensions, price, cover and pages properly). Delivery time of this job and price are the most important items. Thanks in advance.
