Add products to Magento

I have 500 products that need to be loaded on my magento website. I will provide all the content, "the word" for each product, and images. Each product will have "one word" that is different, as all the products will be the same except for one word and one image that will differentiate each product. I will need this done when loading each product (assuming I create 500 copies of one product for you to work with as a template): - change one image - change 3 link addresses with the "word" for that product - change the category position so that the products are listed alphabetically - change the "word" in the short and long description - change the SKU and URL with the "word" - change the metadata with the "word" Please let me know if you have questions. Thanks.
