You mean "copy-writer" as in "one who writes copy (text)". And I don't think you need someone else to write your copy. I think you just need someone to make small corrections to your copy. You need a "copy-editor".
I think it's important that the voice is yours, even if someone else helps with the grammar and/or spelling. Your English is clearly good enough to communicate what you intend to say. It just needs a little tidying.
