Architect drawings of our external canopy structures

Design details: we supply and install aluminium canopies to schools etc and work with architects. we are needing someone who can draw our canopies onto the plan and elevation/cross section drawings sent to us by architect. I have CAD drawings of the system already so i don't actually need CAD drawings done but it is when architects say 'send us a drawing of how it will work on this building - how far it will project from the building, where the posts will be etc'. I want to be able to send a PDF to you and you add in the canopy to the drawing, or take what info you need from the architects drawings to show in the same scale what the canopy will look like.

I have attached an example drawing.
