That's horrible! I'm so sorry this happened to you. I can't really say what the exchange is, or if they do it, but I am willing to donate some Chroma so you'll have extra funds for this.
If all else fails, there's a guy who sells magic goods to Moonblessed. He may have some kind of summoning materials.
