SO, the basic concept that I have for the ship is something like this:
A transport vessel, one that can travel through space and store rare materials in its hold, to be transported to a planet where they can be sold. Possibly with special containers that can adapt to the needs of specific items, like plants.
Big enough to hold at least a week's worth of these materials, plus whatever the crew member(s) need. I don't want it to be terribly huge, but if it has to be, then okay.
But there's only going to be one person piloting it at first, so it has to be something that can be handled by one man, but not really easy to pilot alone.
