Upload Products to Magento

I have a Magento store. I need to upload a lot of products. I have a list of about 100 already, and I am working on a list of another 100. After these are uploaded, I will have about 5 more every week. I will provide you with the list of products, as well as their prices and other info you need. You need to login to the admin of my Magento and input the products, including uploading pictures, and filling out the specs correctly. You will have all this information before you start. Please write your bid for inputting 100 products. We can start within the next few days. Thank you!
