I'm always looking for donations. More specifically, soul donations. Contribute to a good cause, would you? Come on up and offer me your soul. Not like you're going to use it, eh?
I'm not joking. Give me your soul. No, I don't need you to sell me yours, this is not a capitalistic project, and it's fairly obvious that I'm not that rich or capable of granting wishes or clever accidental deaths. I simply accept donations.
So mail me at firstname.lastname@example.org and I'll arrange everything, write up the relevant documents and get the ol' soul running. I'm very willing to discuss it in further detail, and I will accept a soul donation even if you don't "believe" that you have one, so it isn't stopping anything.
Think about it.
