3D cad design of selection of Timber Buildings

We require someone to complete an already started 3D project to produce a selection of 3D models of timber buildings (Timber Horse stables and Timber Garages). The buildings are made up from modular components and many of these components are repeated in the different buildings so each one will just be a variation on the previous one. The work so far has been completed on AutoCAD and the first building is probably 90% completed so many of the components such as roof sheets, timber cladding etc are ready to have materials added. We will also require an environment setting up in something like 3ds MAX to enable us to render the images from a number of repeated camera angles with a realistic background. There is a photo attached showing the current stage of the project and will give you an idea of the required buildings. For the right person there will be prospect of continuing work as we continue to develop our buildings further.
