Industrial product design and 3D visualisation of a charity coin collection unit

Design details: We have a client who is looking for the design of a 'coin collection unit'. The unit will be manufactured in either fibreglass, plastic or metal (or combination).

The unit is being designed for a charity to collect coins. It will be situated at various outlets and will feature a clear panel in the middle so people can see some of the coins that have been collected. The rest of the unit will be of a solid material where there will be advertising. The design will need to be completed ready for manufacture.

We have attached initial rough sketches of the unit and some very low quality renders. It's important to note that the client will want to speak directly to the designer before commencement to explain some of the features of the unit. We will need to be in contact with the designer via e-mail and telephone throughout the process.
Ideas for the visual style: See attached rough ideas

Extra notes:
- Middle section will be 10mm Polycarbonate bent as one piece.
- Bottom section 1100mm tall
- Middle section 400mm tall
- Top 700mm tall
