Design Face lift

We currently have a design layout of six pages. However, it doesn't look fresh or professional. We would like someone to take the current design and change it. I have attached the designs. Please take a good look at them and be sure of the price estimate you give me. I'm not looking for a very small change. Change as much as you like but don't drift off into a completely new tangent. If you feel it is necessary to do that, please be clear up-front. This is why the images have been attached. Please be very clear with your timeline. Also, give me references of the work you have done.
