Do some 3D Modelling

The purpose of the drawing is to deliver a product use-case for a student business plan competition. We are developing a technology that promotes rural electrification in India. The center of the technology is a smart device that enables a power sharing network (A rough CAD drawing of the device is attached). The idea is that each house in an village has one of these boxes. One person has a solar panel. With this device, the person with the solar panel is able to share his electricity with his neighbors, allowing them to power lights or charge their cell phones. We would like to depict this use-case in a professional 3D drawing. We are thinking the drawing will contain 2 or 3 houses from an Indian village. One house will have a solar panel on top. Our device goes inside the house or by the door, where people can plug in their lights, cell phones, or simple DC fans. Ideally, the drawing would be made in such a way that the inside is also visible (perhaps the house has a large door or opening. Also, it would be great to have a few people using the cell phones or fans that our device helps power. The houses should look something like ( [login to view URL] ). To avoid the complexity of drawing Indian houses and people, we are also open to integrating actual photographs into the drawing if you have experience with this sort of thing. Ultimately, we want the drawing to look professional and not like a video game. If you have questions, please let us know as we have a lot of specific details about what we would like.
