3D Product Design in Sketch-up

Description

I need a 3D product designer to develop some concept designs, creating outline specification drawings to show materials and sizes, using Sketch-up, placing the 3D designs into a model of a building that already exists (see screengrab). There are around 12 products to develop to a similar level of detail to the samples attached to this post. A very detailed and full briefing will be given on Wednesday 21st June and we need completed drawings for a client presentation on 7th July. We anticipate a bit of toing and froing until we get the detail correct - perhaps 3 rounds of amends. The products differ in the level of complexity - some are simple recessed signage, other include some audio-visual elements which will be used by visitors to a museum. We need good, rendered models and someone who has a decent knowledge of materials and finishes used in product design.
