Just do the following:
Make it look nice, a well presented cv will do much better than a crappy looking one. Everything written should be relevant to the job you're applying for, don't expand on anything that doesn't fit. Keep everything simple, I'd shorten your paragraphs on jobs and add more bullet points, people can't be bothered to read big bits of text when they have 200 cvs to go through, put the most important/relevant stuff first.
"I am completely confident that I can do the work to a very high standard, and a standard that you expect! "
Do you think they will expect you to work to a standard that is different to very high?
