Project Management Workflow Diagram Design

I'm seeking a talented and dedicated professional to create a comprehensive mock diagram of a project management-based workflow system.

Key details:

* The core use of this system will be project management, meaning the diagram should have a keen focus on functionality that supports this use.
* While I haven't specified particular elements to be included, you should ideally utilise your expertise in project management systems to determine essential components. However, you can assume classic elements within project management systems such as task assignment, progress tracking, and collaboration tools are very relevant.
* The work on this shall commence as soon as possible with a deadline in a two day time.

Ideal candidates will have:

* Proven experience in project management software design
* An understanding of project workflow trends
* A portfolio showcasing excellent diagram and mock-up design
* Fast turnaround with high-quality execution.
