That's pretty cray-cray. I feel like you could just create a CloudFormation template, have a "Launch Stack" button, and get people to pay you to maintain it for $10 / user / month and have a company easy-peasy. Throw in backups via Batch, I think they use EC2 Spot instances so its crazy cheap.

I get that you should always charge more if possible, but I'm much more concerned with surviving during hard times, and there's just less to ablate away if you stick more or less to first principles.
