Do some 3D Modelling

I am looking for a simple 3d model of a 10-12foot long enclosure of a pod. This enclosure will have to accomodate a seat, ventilation and an open and close wing type door or something with hinges. I have attached several examples of similar objects to use as a reference. The critical piece will be that the 3d model needs to be rendered in a glossy format, similar to painting a fibre glass surface (or similar to glossy car colour), preferably in white or light blue or purple. Requirements: - do not exactly match the sample images, this should be an original render - does not need to be sphere shaped, can be cocoon or rectangle but needs to look modern - must have space inside for full adult and seat
