Design a powerpoint template & email footer

As a company looking to create a professional, cohesive look for our communications, we are looking to have a custom PowerPoint template and email footer that reflect our brand. We would like the overall color scheme to be custom and the style of the design to be corporate. We would like our logo to be featured prominently in both designs as well as some of our contact information. This will ensure that our clients can easily identify our presentations in their emails and understand that they're representing our brand.
