Model a handful of power poles in Blender

You will see I have posted another project about making blender models of birds nests. I am very interested in talking to freelancers who can do both projects. The goal of the combined project is to make synthetic photographs of power poles with and without bird nests in them. The challenge is that we want to synthesis pictures of these birds nests when they are partly obscured by the "furniture" on top of the power poles. I have attached 15 pictures which show various kinds of power poles and the sort of things that exist on top of it. I have another 12 which I will share in our discussions. Your job is to pick 5 of those power poles and model them accurately enough that we can place a birds nest on any of the flat surfaces on them, and that parts of the nest will be hidden by the rest of the model you have created. I'd like a mixture of easy ones and hard ones (e.g. sub4 is pretty easy, sub8 is a bit more complex).
