Sketchup model rendering

I am looking for someone (UK) to produce (photo) realistic images from my initial SketchUp models (see jpg) to help me launch a new product range. I have a number of images I need working on, though I would appreciate a range of options from simple, quick renders at low cost (for large volumes, low resolution web images) through to the most photo-realistic work on a small number of images. Please respond with images from your portfolio of similar work.
