Our idea is to give a time limited trial, with unlimited users but with some storage limits.

Plus everyone will be able to cooperate with external contractors for free - you can add as many of them as you want and their accounts will be fully functional but with a few limitations.

For example instaed of sending an email to someone - you can send a task (the form is nearly the same), automatically creating a free account for that target user. This way you can keep track of the request and ping him if he forgets, store it in your project hierarchy, etc. And the recipient gets it through email and can reply only via email without even registering.
