Critique Brochure and other copywriting

We have developed a very smart product and we need an expert in copywriting with the ability to use the very best of wording and pictures to present our product in the very best way it can be presented. We do have information to work from which makes a good start point and will produce as much documentation and explanation of our system as is required to ensure that the successful incumbent is not hindered. The incumbent needs to have excellent english skills with a good grasp of the english vocabulary as word-choice is extremely important. If possible, the incumbent will also be able to produce the final files (in publisher or other medium so as we can have reproduced in print). Some examples of your work would also be appreciated.
