I need a PowerPoint designer

Kind of design: Full presentation
Data and special elements to include: Infographics and images
Ideas for the visual style: Modern but not too complex - must be visually interesting but still showcase the key content
Preferred colors: White and light green
Extra notes: I need someone to make a powerpoint presentation look more slick and professional. Essentially, all the copy will be written, I just need someone to go through the presentation and make sure everything is aligned, add some relevant images and possibly a couple of infographics. This is for a new business pitch so all work is confidential.
