Auto Ordering Software for eBay / Amazon UK

Hi, I'm into the dropshipping business and I would need someone who is familiarized with eBay and Amazon structure. Please see below requirements: - extracting buyer's full address, custom label from eBay for the relevant order - inserting address on Amazon - searching the item on Amazon based on the custom label - completing the purchase from Amazon I tried to make it simple for now, but there are a few more details to be added along the way. Amazon uses API keys, but this shouldn't be an issue for now. I'm using already an online system that does the auto ordering for me, however I would like to customise it for my needs. Please only reply with an offer if you know how this works, especially on Amazon. Many thanks. Kind regards, Alex
