Add (1000+) products to OScomm

Hello, I have an Oscommerce store which needs products added. Approximately 1000+. How? My distributor has a website. Old fashion as it sounds, they do not have a database/any system in place. So you must download images directly from the site, as well as retrieve all info from the website. So the task - directly save all images/product files. Upload them to my store, as well as manually input "each product" into the admin area of oscommerce. It will have about 7-10 input areas. Brand, price, sale price (if applicable), weight (if app), etc. Nothing too intricate with regard to "adding products". However, it will be high volume. Please advise if you've worked with OScomm before. I will need this completed within a few days. Thanks for your interest.
