I am writing a PP presentation of 25 – 50 slides to be given in Sept over a Zoom type service. I would like help professionalizing the slides with a slide master, transitions, animations, and other features. I have some understanding of these features but desire a more professional result. Slides will have photos, text, tables and expected turnaround is 5 days initial and 1 - 2 days for fine-tuning, simple corrections or modifications. Please quote cost estimate within 10 – 15 %.
