Graphic design template layout for Operations Manual

I create operations manuals for small businesses and I need a layout template created that I can use for each business I create one for. For the most part the structure and content bases are the same and I can show examples and exactly what I do. The problem is they don't look corporate and professional enough as design is not my strong point. I require a template with the following: ( either word or indesign) - some simple generic graphics which I can change the colors to suit the individual businesses but keep the same look A text and headings layout design for all the position descriptions...flowcharts and tasks etc that make up a manual. Any more information pls dont hesitate to contact me
