Hello, a peek at my Profile and you will see some key indicators relevant to your project. I am Top Rated, a designation awarded to me last year by Freelancer.com in recognition of my consistent high ratings from both new and repeat customers; badges, testing, 100% completion rate .... but most important are the Reviews, and if you note the titles you will see that 95%+ of my work is using the PowerPoint tool; my specialty.
The Master Slide Deck is a deep dark mysterious place that I have mastered. I will embed both the design and static elements into the MSD. Titles, footers, slide numbers, font colors and size - even bullets will be consistent. Embedding the brand colors will ensure that each time you insert a table, graph or SmartArt it will appear in your prime color, and a quick click on the color wheel or popdown gallery will give you numerous choices in monotone or your secondary colors. Normally, I only need your logo to take of this (and that logo will also appear on most of the layouts) I will create 20+ unique layouts suitable for your offering and they will contain a variety of placeholders for you to insert both text and images. No more slide after slide with the same look. I will also create a cover, section breaks, intermissions and a thank you slide.
Have a look at the gallery - due to NDA they are very sanitized but give you an idea of what I can do - and the Reviews will provide you with a level of comfort regarding my skills.
Cheers, Wendy
