I need exterior drawings for a property

I need some pictures of a view from my home which is looking out onto my garden. My neighbour is planning to build a vey large extension onto the side of my home which will block out some view and light and I need the pictures to show the view currently (which I can send you a photo and plans of to create image from) and the view after the large extension is built (essentially it will appear from our view as a large wall (6m long by 3.25m high). I have the details of their plans so can include them. I need the drawings to show the loss of sunlight and view that their extension will bring to my home. I am not sure of the best way to show this, but perhaps you can do this with your experience?

I probably need 2 images of how things look now and 2 of how they will look after. Perhaps one looking from the back into the garden and one looking at the property from the outside.

If you have any examples of work you have done and ideas how you might show this to maximum effect as we have to demonstrate our objection to this extension most effectively.

We have a tight deadline as the objection must be made within a few days so please only apply for this work if you are available to do the work within 3 days.
