Hired map with wild deer (9)
I believe the answer is:
chartered
'hired' is the definition.
('charter' can be a synonym of 'hire')
'map with wild deer' is the wordplay.
'map' becomes 'chart' (chart is a kind of map**).
'with' is a charade indicator (letters next to each other).
'wild' indicates anagramming the letters.
'deer' with letters rearranged gives 'ered'.
'chart'+'ered'='CHARTERED'
(Other definitions for chartered that I've seen before include "Professionally qualified - not scheduled" , "Hired privately" , "Engaged" , "Hired, a boat perhaps, for exclusive use" , "Leased" .)
