Integrated UnderwritersLogo Design Contest

We are a wholesale insurance brokerage representing 20+ integrated workers` compensation insurance programs.

Dark Blue, White, Silver, Red, Yellow

I want to use American patriotic colors Dark Blue, White, Silver, Red with small amount of yellow. Remember my agency specializes in integrated insurance products this means that we bundle and or integrate business services such as payroll processing with workers` compensation insurance so being able to use imagery that reflects a our program integration is important.
I think this can be accomplished by integrating the letters I and U for Integrated Underwriters. I like the idea of creating something that is similar to the superman logo using a shield and integrating the letters I and U into the shield. See the example logo I have attached for your reference. It is important to use all the colors requested so the graphics has some depth. I would also like the image to have some depth almost 3 dimensional not just a flat image. See the attached 3d logo images as a reference.
