We all know it's really hard to get good pricing and cost information.

We have a free Asana license that covers my work. We don't have any costs associated with it.
It has a free version.
Asana has two different types of structures: company vs workspace. Company is really best if all the users you plan to assign work to are all internal (have the same corporate domain in their user ID email address). Once one person signs up (even for a free account) with a corporate email address, Asana will automatically relate that person to that company, if it already exists. If you plan to use it for external collaboration as well as internal, then creating a workspace is a better approach.
The price of this solution makes it quite accessible, and the plans fit my budget.
