So we are currently testdriving Jira (and some other products) to see if it fits our project management needs.
We are a small company (10 people), who provide consulting services to a variety of customers.
We have different kind(/type) of services we provide for our customers, which we would like to track in Jira, so it's not just floating somewhere in a consultants head 
Most of those projects require multiple people to work on, so thats why we are looking for a good tool to help us keep track.
Those projects(/services) for customers could last from a month up to 2 year (or even more). Also some customers could have multiple projects running at the same time.
I'm now thinking of what could be a good way to set this up in Jira.
For example, should we set up a Jira Project per customer, and drop all projects for that customer into that Jira Project, or should we set up a Jira Projects per project, so we would have multiple (seperate configurable) Jira projects?
Another important thing is that we want to standardize our projects, so it would awesome if we could easily create a new Project and have some default issues and status types automatically created. (maybe via templates or something?)
When i search around for this 'feature', i can't seem to find much, although there are some paid plugins that are still quite a hassle to achieve this 'simple' feature.
