Really cool graphic in multilayer PSD

We need for our landingpage on [login to view URL] a graphic which we will animate. therefore it needs to be a multilayer psd so that we can switch on and off different layers. We are a green market platform and offer to home/business owners who want to invest into upgrading their properties with renewable energy sources or energy efficient technology. As results of the search we present reference projects from companies. Out of these references the owners can post their project onto our platform, not unlike on freelancer.com Our idea is that we show a nice graphic of a house standing in a garden with a carport and an electric car and bike. The house should feature: - photovoltaic panels on the roof - solar thermal panels on the roof - the heating circle with the heater in the basement and red pipes going out and blue coming back - something that features the steering technology of a smart home - insulation on windows and walls - a wind generator in the garden - photovoltaic panels in the garden (symbolizing pv projects on free fields) - a carport with an e-car , e-bike and e-bicycle all that should be visible in a grey graphic as if faded out. Yet it should be clear for people that they can play and click on those features. So invite them somehow. What we want is that people click on the several features rather than entereing by hand what they are looking for. furthermore, we need on the left a graphic symbolizing the investment. on the right a graphic symbolizing the savings or the efficiency. Example: I want a new heating system and an e-car. So I go to [login to view URL] and click on the heater and the e-car which are now in colour and highlighted. The investment symbol shows a movement. The savings symbol too. I.e. investing in a heater and in a car brings the oinvestment into the "red zone" , the saving is 30%. To be able to show that we again need layers here. Please be aware that we try to avoid flash. Our search engine will then show relevant references. Please take the freedom and propose the proper background design of the landing page if you think the current one is not good at all. Please understand that the graphic should not be too technical, We are addressing people like you and me. So it is important to make it simple. If it is funny yet not too childish you hit our nerve. Feel free to take this idea as guideline only.
