I have been trying to think of ways to make the economy better so I have came across this
http://dev.bukkit.org/server-mods/shopkeepers/pages/creating-an-economy/I am thinking about setting up the shopkeepers plugin, I know we advertise as not having admin shops but I think we need a shop where people could buy the spawn eggs to create a shopkeeper and maybe we will add some awesome enchanted items for sale every now and again. Admin shops would only sell villager eggs for the shopkeeper plugin. We would set up a small admin shop for this and this is also where you would find the tools/weapons/armour every now and again.
I also think we should turn back on creeper damage for the reason that,,, since the server has been running almost 6 months now you guys know that griefing is non existent so why do you need to bother protecting your builds. Build protection was only purchased to really stop creeper damage and or monster spawning.
Off the top of my head we would sell villager eggs for 5-10k each that you could then use with this plugin
http://dev.bukkit.org/server-mods/shopkeepers/That villager will give you the ability to make upto 8 trades
As for tools/weapons we could make something like a sword with sharpness,looting,fireaspect, smite etc and sell it for a crazy price
The whole point is to get the economy working properly and not just have players selling items and not doing anything with their money
