I would instantly subscribe if there was a 10$ subscription per month. I don't need all of the premium features. A simple Basic+ with more speed and storage would already be a fine deal.
Out of curiosity, have you looked at some of the other hosted copies of GitLab? They have "marketplace" listings in AWS, Azure, and GCP, and I'd bet other cloud providers have a similar "click button, get GitLab" setup. This train of thought presupposes that the $10 you want to pay is to have someone else run the compute, "s3", database, and runners for you, versus "self-hosting"
