Do some 3D Modelling

Hello, we are a new home building company in New Zealand. We need to create some images for our website based on our floor plans (please see attached as an example), at this stage about 10 of them but potentially on-going work. 1) We will need for the floor plan to be turned from 2D into 3D. 2) We will need a similar styled 3D of the house in concept from the outside, with trees, grass, sky etc **This does not have to be super flash or fancy, just so our clients can get a good idea of the plan!** For examples see the links: [login to view URL] [login to view URL] If you can, please provide: -An example of similar work. -Cost for one house; 3D floor plan and 3D house outside. -How long you think one houses would take (no rush, just to get an idea :) Thank you!
