As you are starting with Excel sheets I would use the other Office applications to standardize the formatting and generate the pdfs. I have done this same thing for my office and could quickly reproduce that work.
I have more than twenty years of experience organizing, developing , and publishing briefings, proposals, and other documentation. These have included military operations, network design, project tracking, and decision briefs. While completing my Master's degree in Telecommunications and Network Management I authored several papers that included security plans, project proposals, and business analysis. This included advanced work with Excel utilizing pivot tables, linked formulas, and pull down lists, organizing information in Access, and developing diagrams in Visio.
