Same here. I have accumulated a good amount of discounted accounts like you in time.
infestor is for the people like us, you create gift codes, and people claim their accounts with these codes:
Example:
https://steemit.com/steem/@emrebeyler/free-steem-accounts-first-come-first-serve-no-strings-attached
However, setting up infestor requires info on deploying a python app. Maybe, I can make it heroku friendly in the future, so people can serve it with a 'one click deploy' link.
This is super cool, gonna check it out! Have you played with some of the free-tier AWS stuff? Might be able to get away with that.
free-tier AWS should be allright. The app doesn't need any real resources. Just a Python3.6 interpreter and a web server. :-)
