Here in England as a church organist I ask for 20 pounds, which would be around $35 I think.

As it's someone you never met, you have to treat it as a job... hard, I know, but just think what the undertakers are charging!

It's worth finding out who the undertakers are - they may well deal with it on your behalf; that often happens over here, and it helps smooth things over. They don't usually expect to be paid an agent's fee for doing so.
