Hosting a git repo and a very very basic issue tracker is so not worth $2500/year. Not to mention that even this isn't a fixed price and it grows linearly with the number of employees.
GitLab provides the same service for free. Well, at the cost of "you reading the manual and installing it on a VPS", which takes between "minutes" and "a couple of days" depending on how deep you want to go. A VPS that can easily - easily - scale to the needs of 100 people is "$5/mo".
Looking cool and having brand recognition will indeed earn you money, but everything has its limits.
