Hello and welcome along, to the hobby, the game and these forums!
Trading resources and as an artisan is a longer game than some, but can be lots of fun. You will end up putting in the legwork as you go back and forth!
As a starting point, get a personal resource that supplies you with materials, and artisan recipies that will sell well (a whole topic of it’s own, but very simply, the simple and popular stuff sells better than the huge flashy things: they only last a year anyway).
Try to find some friends or a large group to join, to ensure they have resources you can grab some of, in exchange for magic items and more resources. Go back and forth selling what you make and what you have, selling high and buying low. Note that artisans can Bond items they know how to make.
[ Magic items have to be magically attached to the wielder to be used. This takes a small ceremony and a few seconds, and needs to be told to a referee to have it officially logged. Mages can do it with any item, cos magic. Artisans can do it with the items they know well, cos they know the blueprints.]
You can certainly end up throwing around piles of (personal level) resources costing many thrones to make several expensive items commissioned by deep-pocketed clients. Could take you a year or two to get there.
Or you can go higher yet.
High value materials are:
Ilium : Used to make enchantments permanent; Artefact items. The bigger the item, the more ilium needed, and the Empire gets not much a year, across the field.
Bourse resources: Mithril, Wierwood and White Granite. Very expensive (5 thrones each or so), and used on the strategic level (building castles, fleets, armies…).
The goal for these would be to get a Bourse seat, a position that grants you a small pile of the above regularly. At that point you’d be one of the merchant princes of the Empire… ask in your Nation for ways to get a Bourse seat, as methods vary (including syndicates, rotating holders, auctions, and ignoring the whole thing 
).
Getting to a Bourse seat could take years. But it’s a hell of an in-game goal, and not one I’ve ever been able to take more than the first step or two towards. Good luck!
Here are a couple of podcasts by some folk I know. I haven’t actually listened to these precise episodes, but they may prove useful:
