Happy to get parking hired (7)
I believe the answer is:
pleased
'happy' is the definition.
('pleased' can be similar in meaning to 'happy')
'get parking hired' is the wordplay.
'get' says to put letters next to each other.
'parking' becomes 'p'.
'hired' becomes 'leased' ('lease' can be a synonym of 'hire').
'p' put next to 'leased' is 'PLEASED'.
'to' acts as a link.
(Other definitions for pleased that I've seen before include "Content" , "like Punch?" , "Glad" , "Feeling satisfaction" , "Well satisfied" .)
