Construction machine photos for general marketing

We are needing photos taken of our rental construction equipment out working on our customers job sites in Christchurch, New Zealand, these are going to be used for general marketing. This person needs to be able to interact with our customers, to be able to work with them to get the photos. Would be of benefit if you are construction orientated or construction equipment enthusiast. Need to be a very good quality with the machine the focal point of the photo, however the background/setting is also just as important with not too many people or other machines in the photos. We have an immediate requirement for around 500-750 photos, with the potential of ongoing work.
