Consider, if you will, the following paragraph:
You want to produce effective, impactful writing, however after looking it over, it could use a fulsome edit. A good editor can help you bring your vision to reality, avoid errors, and smooth transitions as well as incorporating the interests of your audience, which is of critical importance. Alternately, a writer could be what you need; to create material which is engaging and error-free, present your message clearly and coherently and to insure your message will resonate with readers.
That's the kind of paragraph you don't ever want to be associated with (or perhaps "with which you do not ever want to be associated"). It's rife with errors that will irritate and alienate an eagle-eyed reader, straining her patience and taxing her goodwill. Words matter: clean, compelling writing is an invaluable asset for you or your company.
I have years of experience writing and editing everything from government reports to breaking news stories. I pride myself on cultivating productive relationships with my clients: my goal, whether drafting web copy or reviewing a fiction manuscript, is not simply to save you from misplaced modifiers but to respect your voice and priorities while anticipating your readers' needs.
