powerpoint redesign

I'm looking for a talented freelancer to help me redesign a PowerPoint presentation to be presented to a 400+ person C-suite audience. The purpose of the presentation is to engage and inform the audience, and I have specific elements and branding in mind that need to be included in the redesign. The presentation currently contains 10-20 slides. If you're confident you can take my current presentation and make it shine, I'd love to hear from you! Turn around has got to be quick (24-48 hours)
