Big spender delays start of ambitious moon shot (11)

I believe the answer is:

loadsamoney

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

'big spender' is the definition.
I know nothing about this answer so I cannot tell whether this works.

'delays start of ambitious moon shot' is the wordplay.
'start of' says to take the initial letters.
'shot' indicates anagramming the letters.
The initial letter of 'ambitious' is 'a'.
'delays'+'a'+'moon'='delaysamoon'
'delaysamoon' anagrammed gives 'LOADSAMONEY'.

Can you help me to learn more?
