Architectural render/visualisation

We require an architectural rendering for a proposed dwelling (see attached architectural drawings) The project has been modelled in archicad and little or no modelling work will be required we are able to save this out to a 3ds file or other similar formats. When preparing your cost please allow for a small degree of alteration to the image (materials/colours) after presentation of preliminary image. We intend to print this image on a large format sign so please keep this in mind.
