Please include the logo into the fax template. If you find improvements in the layout then feel free to make those. Let's not overthink this too much. Keep it simple :)
We like The powerpoint concept as is. The slide titles are for some reasons on the bottom. It seems to irritate some folks. If you can switch the slide titles to the top, keep the look and feel of the slides and work in the logo then that would be fantastic.
The letter head should include the following
Salto Partners, LLC Box 1364, Great Falls, VA 22066 Phone 703 672-3720, Fax 703 439 2608, www.saltopartners.com and the logo.
Again, let's keep it simple.
Thank you for considering this project.
