Build a Loan Origin Flow Using jBPM KIE workbench

I want to set up red hat jBPM in a local machine running windows , then build a loan origination flow with all processes and execute it. The process flow must be a little complex involving all tasks and utilizing many features of jBPM. I want to present this as a graduation project and I have only 3 days. I also would need a detailed report of steps and installation and all code.
