Create Power Point document - Visio or other diagram software required -- 2

I have about 5 to 6 slides that need to be created for a software system. I'll do the mock up. You just need to make them into good diagrams. All diagrams will just be a one page diagram with typically 10 -to 20 objects. Send me some examples for software systems.

Update: it's primarily technical diagram drawing, needs to use Visio or other diagram software to produce.
