Of course, if it's an option for you consider using GitLab.com, it offers unlimited repositories and collaborators. Right now we don't limit the amount of annex data but we might in the future.
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.
How many people are you?
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.
