Milk supplier's price racket, daring to pursue a grand

'milk supplier's' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.

'price racket daring to pursue a grand' is the wordplay.
'price' becomes 'fee' (I've seen this before).
'racket' becomes 'din' (both can mean a loud noise or disturbance).
'daring' becomes 'bottle'.
'to pursue' is a charade indicator (letters next to each other).
'a grand' becomes 'g' (G is short for ground as in a thousand).
'bottle' put after 'g' is 'gbottle'.
'fee'+'din'+'gbottle'='FEEDING-BOTTLE'
