Do some 3D Modelling - add two 5x5 metre rooms to a sketchup file of 12x5metre dream house. The two rooms are 1. room 1 = bdrm, 2. room 2 = office. Delivery should be floor plans, sketchup full file and animated video of walkthrough of all areas in mp4 file. My budget is NZ$40. I also have the sketchup file but it's too big to upload here.
