Need 35,000+ product images for client from internet

I am building a website for a client the sells products similar to Dicks Sporting Goods and other outdoor retailers. He has a product list of about 35,000+ products. I have an excel file of all the products with just the product name, small description, and price. The issue we are having is we are using wordpress with woocommerce to sell on the website, and my client doesn't have images for any of his products. His products can be found at various places online and we need somebody to pull pictures for the products as import them to the correct product. If it's easier to add the image to the excel sheet then upload we can mass upload products too. We are doing them by categories so each entry has anywhere from 100-1000 products in between that need images pulled. I have specific dimensions the images have to be in. I know this is pulling pics so quality isn't too big but would like it to look reasonable. I want to break down the list into 4-5 batches and start with 1 batch until we finish all of them. I need somebody experienced with wordpress, woocommerce, excel, data entry, picture editting, etc. Thanks.
