Quickest way to 57 Summoning

[more reasons]

So I've botted 10 accounts to 60ish cb and 54 runecrafting with the intention of crafting laws using the hot air balloon. I stupidly didn't look up the requirements for enlightened journey until just now and there's no way I'm going to get the requirements on 10 accounts so looks like I'm crafting natures with Graahks. What would be the best NPC for me to kill for charms at my accounts combat levels?

botting ghouls or rock crabs even maybe are good for gold to 57.

They are both about the same investment of time if I'm not mistaking. but cockroaches are good charms are low traffic.

croch soldiers are really good too
