Brochure creation/modification

We have a brochure that we want to get new graphics (collages of people mainly) created for it as well as we would like to have a new layout.? Attached is a pdf of what we have now so you can get an idea of what we have and need.? Basically we want someone to take what we have and create a more professional looking set of brochures.? This is not the only one that we need, we have about 8 others (maybe more), but that is another on-going project.? We will also require someone that can make changes to the brochures in the future as the need comes up. My attached sample has a problem with the front graphic, this is being caused by converting the document to PDF.? It's not a design problem.? It's just time to update the look of our documents.
