Names and Descriptions needed to be copied from PDF

We have a little more than 2100 products that need to have the names and descriptions copied from a PDF catalog with all the products. Descriptions for each item must match up EXACTLY. This is not a hard thing to do. We will supply a list of the products by their item number and a PDF catalog that contains each and every item in it. To make this even easier for you we have supplied in the spreadhseet of item numbers the exact page on which the item is located in the catalog so you dont have to search for each one. Also in the spreadsheet will be 3 columns. One with item weight, anther with product dimensions, and the last with the units that it is sold by. This data must be included in each description if the information is present. Attached is a sample description.
