sketchy concepts for a 3D After Effects learning video

Our company has been asked to make a 3d learning module/ after effects video for a batteries supplier. Currently we do not have the time to do this project fully ourselves, therefore we want to partly outsource this project. We are currently in the stage that we need to show a concept. I am looking for someone who can make a sketchy concept how a learning video can explain the differences between different types of batteries. I only need some sketchy ideas which we can present as concept to the customer. So for this project we do not need someone who works out in details different 3D concepts which can be used in an Adobe After Effects solution. In this phase we only need to show a few sketchy images. After successfully completing this project, you can get the additionally project to work out the sketchy ideas into details and finally convert it to an After Effects learning video. Again for this project we only need sketchy ideas. So do not offer a price for other things than the sketchy ideas.
