283418 Magento Cart Product Input

Hello, I need a Magento Cart expert to load products into my shoppingcart. I have spreadsheets that can be converted into .CSV files, but all product info and pics will have to be taken off of the manufacturer websites, I will provide links to all of the sites and assist in any way possible. Please only reply if you have extensive experience with Magento carts and are willing to provide constant communication while inputting products. This project will include inputting approximately 750 products, with the possibility of ongoing support once completed. The images may have to be resized, I do not want them stretched or blurry. I can provide more info for this project if needed. IF YOU DO NOT HAVE ANY EXPERIENCE WITH THE MAGENTO CART PLEASE DO NOT ANSWER THIS AD!!
