What is the quickest way to get exp on a factions server?

I've got a faction in Minecraft and I really want to enchant my bow, however it is taking a long time to get exp from blaze spawners, zombie pigmen spawners, and creeper spawners.

Is there a way to quickly get EXP without using spawners, PVP or using any weapons? Ideally it should also be cheap to do. Thanks!

Solution 1:

If you have access to the nether, mining nether quartz is a very efficient way to gather exp. The abundance of nether quartz and amount of exp it gives you allows for quite a quick grind to level 30 when compared to other methods. It may be considered unorthodox though
