drop shipping cloud software

design a Google cloud-based software that connects one wholesaler's website API to Amazon's website API. I want the software to be simple push button adding products from wholesaler to Amazon all with a simple push button. I need it to be on the Google cloud. I also want to be able to sort out the wholesaler's inventory into niches making it easy to choose a niche to sell on Amazon. I want the cloud software to automatically post onto Amazon with good SEO on each post. I need options as to how much I want to charge for the product put on Amazon. For example -1 under the cheapest item that's similar or the same item or even more than others on the site just make it one size fits all meaning I don't need to do each upload to Amazon just all at once each item is -1 of the cheapest similar item on Amazon. I want to be able to post many at once automated quickly and easily. I want to be able to limit different users amount of posts and able to limit how automated it is for different users. I also need the cloud software to recognize when an item is sold on Amazon and it takes the address and name from Amazon and puts it into the shipping address and name on the wholesale site thus shipping it to the person who bought it on Amazon. Fulfill Orders Automatically with one click and Notify to your Customers easily. If this job gets done well I will do another job for the app on both Mac and Android platforms.
