Brochure Design Templated - 50 bespoke brochures 3 - 5 pages

As part of a large scale marketing plan we are looking to produce 50 brochures for various part of the business. We have 10 completed already so that you can get an understanding of look and feel of the brochures. We are looking at completing these brochures in the most cost effective way while still maintaining the quality and feel of the brochures.
Most brochures will be 3 pages about 10 will be 5 pages. I am not looking for per brochure cost. I am looking for potentially 7-8 brochure designs than to arrange the different content from the brochures word template into these brochure designs.
