I need a PROFESSIONAL Powerpoint created - all content and source info already input

Information for the business: Presentation at professional business conference
Industry: Business
Target audience: Bid and tender professionals
Number of slides needed: 20
Ideas for the visual style: Clean, business, appealing, engaging, fresh, lots of visuals
Things to avoid: Lots of text, unclear points, blurry visuals, visuals which dont make sense
Preferred colors: dark blue, light blue, green, lots of white
Extra notes: I have created a draft Powerpoint of 20 slides for a professional conference I am presenting at. All content for the slides (bullets, some imagery) is there - however making the Powerpoint look really professional is not my area of expertise at all.

I need a Powerpoint professional who can take my slides and turn them into something really amazing - and fairly quickly. If you are interested, please share some examples of your visual Powerpoint presentations. The look I'm going for is clean, business, youthful and a twist of fun.
