Sales Pitch PPT and Mobile App Design

I require both PowerPoint and mobile app design services. The PowerPoint presentation is aimed specifically at potential clients and investors for an impactful sales pitch. Powerpoint might include 1-2 small video clip. The following are my requirements:

For the PowerPoint Design:
* Creative and engaging slides
* 5-8 sec concept explain video
* Incorporation of key sales messages
* Suitable for a highly targeted audience: potential clients and investors.

For the Mobile App Design:
* User-friendly and functional interface
* Attractive, intuitive design
* Reflects the vision and purpose of the app clearly

Ideal freelancers should have proven experience in crafting compelling PowerPoint designs, particularly for sales pitches, and crafting visually appealing, effective mobile applications. An understanding of my target audience's needs would be vital for the job.
