Go for and bring back the money (3,2)
I believe the answer is:
set on
'go for' is the definition.
(both can mean to attack)
'bring back the money' is the wordplay.
'bring back' is a reversal indicator.
'the money' becomes 'notes' (I've seen this before).
'notes' in reverse letter order is 'SET ON'.
'and' is the link.
(Other definitions for set on that I've seen before include "Attack" , "Determined" , "Go" .)
