I am working on proposals in film and advertising industry. Some are to CEO of ad agencies, some directly to brands. Need someone with experience in BOTH business AND journalism to help me edit the content of the proposals. Nature of proposals are more business but the audience is very creative so need to adjust it. Ideally, see this as a collaborative process. I write ideas but my expression of it not always very clear to people. And I am not native Eng writer so by default there are stylistic and grammar issues. SO, overall it a combination of proofreading, a bit of editing BUT big plus would be to look at it as a raw content to construct better arguments.
I am attaching a short text from current proposal - if you can look at it within given above task and send me your suggestions, this would be the best way for me to choose.
Looking forward to it.
