Regular support for PowerPoint Presentations - Concept, Design, Content, and Editing

Need regular support for the concept, design, content formulation and editing of PowerPoint presentations at the very high-design level. PPT's would be for corporate clients, pitch decks, and presentations. 90% of the presentations would be in English, and maybe 10% in Chinese (not a major problem if you don't have Chinese capability). PPT's should be custom, modern, and striking.

Drafts of slides will be sketched on paper via hand (scanned and emailed to you), and then it is your job to make it look pretty, nice, presentable and professional.

Please quote your price on either a per slide basis, or some other way to have a fix predictable cost.
