I'm a technical engineer in a bolt and nut singaporean local merchant, we have over 10 new salesmen that has zero knowledge of fasteners, so I have to create a ppt slides to teach them the basic knowledge, I need it to be balanced in text and image, not text heavy, around 15-20 slides, white background, black fonts and simple line images, unless the color is necessary. ask me any question if you are confused before proceeding.
