Amazon Seller Central Automation Via XML Data Feeds

I am starting to sell on Amazon. I am a Pro Merchant looking to automate the inventory and order process from Amazon to my supplier. The task will only deal with 1 supplier for this project. If this project is successful the same can be done for additional suppliers that I plan on bringing into my Amazon inventory. What I am looking to automate: Inventory Updates: Scheduled throughout the day for items that have changed in quantity. New Orders: Automatically send orders to supplier. Shipping Confirmation: Retrieve shipping confirmation from supplier and update Amazon. The supplier provides real time data via XML feeds for everything that I am interested in above. I need someone that can take that information and integrate with my Amazon inventory.
