Amazon catalogue upload

We need an experienced e-commerce handler for uploading our catalogue on Amazon. We are a Canada based furniture retail company. We already have more than 100 products live on Wayfair Canada and now going live on Amazon also. Descriptive information is already available in our companies dropbox, to which we will provide full access. For the time being we need to upload 24 products on Amazon with detailed description. Self-added description is also allowed.
