How to monitor Job/Task progress via a report

I have a job that contains many sub jobs and tasks.  I am wanting to create a sql query that will show me where each client is at as it runs the job.

For example

I have a job called "Test Job".  This job has 3 tasks, "Test Task 1", "Test Task 2", "Test Task 3".

I can schedule the job against a client, Client1.  The client has completed task 1, and is running task 2.

Client Name - Job Name - Last Task Name completed - Current running Task Name

So my ouput would be the following:

Client1 - Test Job - Test Task 1 - Test Task 2

Things I know:

Client GUID

Job GUID

Any ideas how to accomplish this?
