Images needed for product website

Hi I have a website with about 3800 products that need images. The images can be found online by searching the description or SKU (most skus that we have on the site are the actual product ID from the manufacter but we added a few digits in the front with a dash like: MLC-530019 ZUD RUST REMOVER 19oz LIQUID , the actual item# to find online is ZUD 530019 ) So this needs some research and time to make sure its the correct image. Images will need to be saved to a folder with the SKU as the file name. I will give the site URL to possible candidates.
