PowerPoint should be 10" x 6.25" (on-screen show 16:10) landscape.
To save your time, you really only need to design 3 content layouts: 1 title slide, 1 subtitle slide, and 1 basic content slide with heading/body (could be text or image). However, we'd prefer to have two color schemes for each of the 3 slide types. Please refer to our website (http://www.idgconsulting.com) to get an idea of colors that would complement our business (shades of teal, blue, and earthy green).
Our previous PowerPoint was primarily two-tone and the next one can be as well, but doesn't HAVE to be. However, one thing we would like is to be provided with a palette of 6-8 complimentary accent colors that we can use for graphs/charts.
In terms of font, we would like to use a font that is clean, simple, sans serif, and easy to read, but most importantly, is a default font setting on most computers.
If you'd like, you can incorporate globes or video-game themed images into the design. However, any video-game themed images cannot be too obviously associated with any particular game, franchise, platform, or company.
