Quick fix, fantastic load of money saving corporation, finally (5,4)
I believe the answer is:
magic wand
'quick fix' is the definition.
(eg in 'I can't just wave a magic wand')
'fantastic load of money saving corporation finally' is the wordplay.
'fantastic' becomes 'magic'.
'load of money' becomes 'wad'.
'saving' is an insertion indicator.
'finally' says to take the final letters.
The final letter of 'corporation' is 'n'.
'wad' going around 'n' is 'wand'.
'magic'+'wand'='MAGIC WAND'
(Other definitions for magic wand that I've seen before include "Fairy Godmother's baton" , "Spell stick?" , "Spell-casting stick" , "Wizard's tool" .)
