A client wants a presentation design that he can edit and change after, including elements such as: template frame, body copy, lists, calls-to-action, animations, custom vector graphics, mockups - you get the point!

What is the best way to undertake this? how do YOU design presentations? is there a way to design in PSD and convert to PPT? do you work directly on Powerpoint? (Feeling lost)

The final outcome should be: Inatilized design delivered in PDF and templated Powerpoint format that can be edited! for future use

Thanks!
