Money specialist in e-business backed on film (9)

Ross

I believe the answer is:

economist

I'm a little stuck... Click here to teach me more about this clue!

'money specialist' is the definition.
'economist' can be an answer for 'specialist' (I have seen 'Financial specialist' mean 'economist' so perhaps 'specialist' could also mean 'economist'). I am unsure of the 'money' bit.

'e-business backed on film' is the wordplay.
'business' becomes 'co' (short for company).
'backed' is a reversal indicator.
'film' becomes 'mist' (to film over is to mist or fog over).
'on' reversed gives 'no'.
'e'+'co'+'no'+'mist'='ECONOMIST'

'in' acts as a link.

Can you help me to learn more?

(Other definitions for economist that I've seen before include "John Maynard Keynes for instance" , "He studies money etc" , "Financial expert" , "Expert on finances" , "Expert in all aspects of wealth" .)
