PC certain weapons

First of all since i'm looking to purchase one I need a general price range on a r9 gold embercrest staff.

Also I would like a PC on:

a Serrated Spear, r10 gold with perfect caster mods (+5e, 20% enchant).

And

a Crystal Flame Staff, also r10 gold modded with 20/20, +5e, +20% echants..

Thank you

rq9 embercrest 20k imo

serrated spear 20k

crystal flame 20k imo...
