We have a 6-page design brochure that needs to be updated to match the brand for which we're targeting. You would need to go out and find the logo for the brand, app icon, app screenshots, and other assets to complete each brochure.
To start with we have about 10 brands we're interested in targeting. That number could be as many as 50 over the next month.
You could be using a combination of Keynote, Photoshop, and Illustrator.
