Sod the money - think of all the porn films you can star in! It's always the plumber who turns up and she can't pay. (So I've been told!)
All the best!
Here's a limerick for you :-
There once was a plumber from Leigh,
Who was plumbing his wife by the sea.
She said, "Stop your plumbing"
"There's somebody coming"
"I know", said the plumber, "It's me!"
