Even the greatest treasures can be underwhelming with poor delivery and discovery. If you're looking for concise, accurate analysis and technical expertise, I humbly suggest you conclude your search. I work as an investigative analyst for a leading healthcare company in my state; my natural element is detail-attentive translation from massive spreadsheets into a cohesive format that leadership can act upon. You've done your part in getting the content together. Let me do my part to make sure all the little nuances and grammatical detail only serve to reinforce the value you've created. At best, readers are going to be subconsciously distracted at poor punctuation placement and miss the content of your text. At worst, you may inadvertently convey a whole different message than intended (flashback to the "let's eat grandma" lessons). Ultimately, presentations aren't for recreational purposes. You've created it for a distinct purpose, and a sub-par presentation may jeopardize that. If you can get the material together, I can shape it into something that leaves your audience with a clear understanding of your goal. Ever the devil's advocate, I can also identify some areas in your presentation that may need a little more support, if desired. If what I've described lines up with what you're seeking, I look forward to hearing from you.
