4 different buildings

I need 4 different buildings drawn next to each other, not very detailed, yet blend together when side by side. Maybe just line or frame drawings in the same color? We need them to describe 4 different installation we do with our "Green Energy carbon reducing solution." 1st building is a typical 4 story apartment building (25 apartments) probably built in the 40's or 50's inner-city in NY or NJ. 2nd building is a 20 story office building also built in the 40's, 50's or 60's. Typical NYC old office building. 3rd building is a 60 story building from the 70's or 80's. Typical NYC office tower. Between the 20th and 21st floors, also the 40th and 41st floors there needs to be a break that looks like ventilation is brought into the building, almost an extra floor. 4th building is the Empire State building. What we are going to describe to the viewer is that the 1st building has only 1 thermostat to control the heat, the second building has 2 thermostats, the third building has 3 thermostats and the Empire State building has only 4 thermostats. The average 40 story commercial building has only 2 thermostats to control heat or air conditioning. Very inefficient. All on or all off creating many hot and cold spots throughout the building. Our solution creates 100's of "Virtual HVAC Zones" to eliminate the problem and save energy. We can make buildings 30% or more efficient. This is our first try on this website. We are doing a complete website but I decided to try small first. These 4 building will tell the whole story about how and what we do to achieve savings. I will include some samples of the buildings I envision. We only need the buildings, nothing else (trees, people, other buildings, etc.). Also I will include a quick video presentation we started to explain the project. Besides these 4 buildings I will need website help, animation work, video editing, presentation packets and installation manuals.
