Artist wanting cash (not yen) before start of task (5)

I believe the answer is:

monet

'artist' is the definition.
(painter Claude Monet)

I cannot understand how the remainder of the clue works.

(Other definitions for monet that I've seen before include "Claude ---, painter (waterlilies)" , "French artist shown in ..." , "Claude, impressionist painter, d. 1926" , "French Impressionist with famous garden" , "he painted Rouen Cathedral" .)

I've seen this clue in The Guardian.
