Write some Software

The software needs to have all the functionality described for Ebay and Amazon control/integration. I am looking for a solution that will keep up to date on popular, trending, best selling items on Amazon, Rakuten, EBay, and all the major online retail websites. The software will need to determine if an item is a good selling item based on how many like units have sold on Ebay and communicate with Ebay stats to determine what is the best price to offer the product for purchase. This software will also need the ability to list the found products on eBay at a user defined price that is a percentage higher than the price found on the original listing. This software will need to monitor and adjust price changes and availability according to the original listing. If the original listing goes up in price it will make the same adjustments on EBay keeping the mark up based on the percentage entered by the user. If the product is no longer available the software will need to end the listing immediately on Ebay. I want the software to be extremely accurate and up to date constantly. This software will need to know how to list items on eBay. The software will need the ability to import photos, product descriptions, product specs, details, all information from the original posting to Ebay. The software will need the ability to optimize titles for highest ranking possible on EBay etc. I want the software to operate all of this automatically. All the user has to do is input initial information needed to access eBay and Amazon and the software will handle the rest. I want the software to work both ways. Gather product listings from Ebay and make postings on Amazon and vice versa. Gather product listings from Amazon and post on Ebay. I also want the software to be able to handle fulfillment and shipping. Example))))) Product for sale on Amazon for $30 the software lists it on Ebay for $50 when the product sells on Ebay the software will use users paypal information to make the purchase of the original listing from Amazon and ship to the address of the customer who made the purchase on Ebay. The software needs the ability to do the same thing if the original listing is on Ebay. User needs the ability to enter products manually if needed. The software needs to constantly add items within Ebay or Amazon guidelines. Basically the software will be a fully automated online store
