I need graphic design help for powerpoint training material

Goal: We are providing bank data management training, and need a graphic or set of graphics, in powerpoint, to illustrate how banking data moves around the financial system. The graphic(s) need to illustrate conceptually: - How people interact with financial institutions - write checks, make deposits, send wires, etc; - How financial institutions pull information out of those interactions and store that information internally; - How that information is used by the bank - transformed into reports, bank statements, etc; and - How the information is shared with government agencies for regulatory and law enforcement purposes. Target audience are bankers, regulators, and law enforcement people - experts in their field but not necessarily data- or tech-savvy, so we’re seeking a crisp and modern professional look. attached is a ppt with an ugly illustrative cartoon treatment for what the art might depict; and some example images (copied from the Web, and used ONLY FOR ILLUSTRATIVE PURPOSES, NOT TO BE USED WITHOUT SOURCE COPYRIGHT APPROVAL) to give a sense of what’s already out there, that could represent look & feel of what’s interesting. We would like an initial set of basic graphics depicting this process. From that initial set, our trainers will work with the graphic designer to fine tune the graphics to meet the training requirements.
