Yes, I could proof and edit your presentation for you. As it stands, it is about 2,900 words. If the remainder of the document is represented well by the sampling that I read, it could be done in fairly short order. I do want to thank you for posting the entire document for us to look at. And knowing that it is to be read aloud is a big help, too.
Because I know the nature of the editing that is required I can offer you specific discounts that I could not suggest if I had to guess about the text in question. Thank you again for that.
I can do what I call a proofreading and basic edit of this material for $133.00USD after Freelancer.com fees are added. My normally quoted rate would be $70 per thousand words, if the material was sight-unseen. After website fees, that would run the bid up to $233.
I hope I can help you with your project. But whomever you select to do this for you, I wish you well with the project. Thank you for the consideration.
Dan
