I like the product. But I wouldn't invest in automation of all the stuff upfront. I would just process the upload/order manualy for a couple of first users just to validate an idea financially. From my experience people fear more of success than failure therefore overdo the product to survive an imagined scale explosion. But there wouldn't be much outrage from users that once flooded you have just raised the prices or temporary suspended the service. I guess queue with bucks in front of the door would boost your motivation to finish up the process implementation in half of the time.
