Make a cannonball run to Redcliff. I'm not sure if it's possible at the beginning, but in Redcliff there is a schematic vendor that will get you all the tier 1 and some tier 2 schematics you could want.
It may be you can only get into Redcliff after unlocking Val Royeux though... there is a merchant there that sells a lot of tier 2 schematics, but I don't think you will have the gold for that.
later in the game, when the inquisition really becomes a movement, there will be adviser missions to collect materials, not just gold. Choosing a different adviser, has a different focus on loot grabbed.
also, if you feel it is important to you... the advisor mission timer is based on your system clock... do with that info what you will. I wouldn't recommend doing it for gold... that's game breaking. Doing it for mats however, that cuts out a lot of MMO work, and I kinda approve.
