Build an Online Store

Hello, I am developing a Prestashop E-commerce, and have imported 20,000+ references from 2 different dropshippers (EL & SD). EL has 18,000 references and SD 2,500 References. When I upload the XML for each suppliers each references get 1 picture only and is missing the Dimensions of Products, and the Supplier. I already worked with a Freelancer and for the first supplier, EL, and we uploaded the rest of the images on server and Freelancer created script to upload & attribute the dimensions of products and rest of images to correct references from EL. Recently, I had 2,500 extra references from supplier SD uploaded. Same thing, product dimensions, extra images and supplier information is missing. This time, the supplier does not provide the extra XMLs and images files. So I am looking for someone with skills to retrieve the images and info from the suppliers website and bulk change the names of images if necessary to [login to view URL], [login to view URL], refxxx_img3.jpg...etc for each products so a script can attribute images to related references. Let me know if you're interested. and I will email you the website URLs and necessary information.
