Big money — millions pocketed — for salespeople (8)

I believe the answer is:

tallymen

'salespeople' is the definition.

'big money millions pocketed' is the wordplay.
'big' becomes 'tall'.
'money' becomes 'yen' (Japanese currency**).
'millions' becomes 'm' (abbreviation).
'pocketed' indicates putting letters inside.
'yen' going around 'm' is 'ymen'.
'tall'+'ymen'='TALLYMEN'

'for' acts as a link.

(Another definition for tallymen that I've seen is " Hawkers".)

I've seen this clue in The Times.
