Create a 3D model of a yard in Sketchup

I need someone to create a BASIC 3D render of a yard. I've attached some photo of the yard as it is (will supply many more to whoever wins), and will supply all measurements (hopefully some could be approximated from the photos too). If the file could be sent to me as a Sketchup file that would be ideal. The surrounding wall and nearby building would need to be modelled also. It only needs to be done in a basic way - the purpose is to calculate the best way to suspend a canvas over the entire area, and exactly what angles would be best to anchor this canvas at. Does not need to be shaded or coloured, just line-work is fine. I'm imagining this is a couple of hours work for someone who knows what they are doing - do correct me if I'm wrong though! Thanks.
