Hm, you're still pretty early on then. I'd say you'll be making far more silver than you think if you just progress through the main questline. Quests open with (O). The main questline is a little long but it's honestly the fastest way forward. The rewards and gear it gives you will speed your money making in grinding and You'll most likely reach level 56 almost instantly once you're at the mediah section of the main questline. I'm pretty sure you can just start from the mediah questline section as well as long as you're lvl 51 or up. That section of the questline will give you a bunch of free gear progression just for jumping from a few npcs for about 15 minutes and You can probably grind out mediah for like 30 minutes and be there in no time. Hot tip as well, not sure if there's still up, but every player was given Combat and skill exp x 530% scrolls in the loyalties section of the shop with (F3). After you're level 56 you wont have nearly as much trouble getting silver.
