Depending on the amount of mats you have, leveling the crafts you need to craft your own exotics can be worth the time effort. Just make sure you have crafting boosters.
Farming in Silverwastes can net you some gold. The basic idea is called RIBA and is basically going from outpost to outpost (Red Indigo Blue Amber) and tagging the events to get bags/rewards. Keep repeating this until the meta's up and then do the meta for more bags/rewards. Meanwhile you can use shovels and keys to get more bags/rewards.
If you really want to make money, transfer those bags to your bank and then open them on a ~level 50 character. You'll get a lot of mats that are in high demand and, aggregated, you'll make a lot of money off those mats + selling rares on the TP.
Things are a little slower in the SW right now with the PoF release, of course.
Hot metas can also get you some good loot but I wouldn't venture into the jungle until you're in full exotic. That place is dangerous.
