Powershell Workflow Show Progress

The project is to show the progress of the Powershell ForEach Parallel loop. I want it to echo out to the console a progress like 20%. It sounds easy but it is not becasue each loop works independent of each other.

Also please be reasnonble on the price as I don't think this project is worth any more then $100.

Please see the attached code that needs to be modified.
