I'm going slightly against the grain here and suggest a Dolphin--small, incredibly fun to fly ship and of the small ships has the most cargo space (but it's obviously not a bulk trader).
Here's the basic setup with grade 1 engineering by Felicity Farseer for delivery missions--long-range ones that take you to places a few hundred lightyears away can pay quite well.
For salvage/megaship scan/courier missions and general frolicking around I suggest this setup.
When buying, shop around in Li Yong-Rui systems for 15% discount. Inara outfitting search is an excellent tool!
