First, craft a pair of Rakata Relics for when you hit 50. Huge boost to HP and they're on use so you can get a temporary buff out of them to improve burst in whatever you're doing.
Also, reverse engineer to learn and make Enhancements,hilts, and color crystals for when you hit certain levels.
If you want to make credits with Artifice, the real money-makers are crafting end-game enhancements whose schematics only drop in Ops or can be reverse-engineered from Black Hole gear. Other than this, Artifice really doesn't make anything that really sells well.
Other than that, check out the markets for lower level crafting mats that aren't too saturated and then just sell Archeology mats (also used for Synthweaving), or Treasure Hunting mats.
Hope this helps you out.
Dread guard relics.
There are DOZENS of very, very lazy people who don't want to do the work it takes to get 350 daily comms. Farm the dailies yourself (and farm the mats while doing them) and buy a dread guard relic, then reverse-engineer. You might get one schem out of six, but when you get the one.. 2 mil or more per relic.
