Unfortunately that's not an option for our (small) company. I'm already using gitlab.com for my own personal stuff, but for the company's, we have to stay on-premise.
5 developers and a few other non-dev people who just use the issues and wikis.
Our pricing takes into account that not everyone is a developer, we have one price per user to keep it simple. Assuming you have 5 non-dev's the cost for GitLab EE would be less than 4 dollars per user per month or less than 7 dollars per developer per month.
