It's always dangerous claiming to be an effective editor and proof reader when you're subjecting your work to public scrutiny. Afer all even The Grauniad recognises its mistakes. After forty years of report writing, preparing articles and books for publication, and publishing pamphlets, posters, newsletters and magazines Dave claims an immodest degree of competency.
Most written copy has a limited shelf life and is soon forgotten but it can serve very important short term purposes. If you need help in producing a newsletter or magazine, if you would like someone to edit or proof read a report or technical document, Dave can provide some examples of previous work. Badly presented or poorly spelled work can affect impact and it's worth building in a little extra scrutiny before committing to print or the internet.
