Anyone want to trade a Vial of the Sands for 25K + captured firefly?

Title pretty much says it.  I've been trying to sell my firefly for 17-19k.  If I ever sell it, I'll just buy a Vial for 40k.  But if anyone has an alchemist and has been wanting a firefly, this could be a good option for you. 

If anyone just wants to buy the catpured firefly outright - I'd go for about 12k?
