Engage the services of gal from Raleigh (4)
I believe the answer is:
hire
'engage' is the definition.
('hire' can be a synonym of 'engage')
'the services of gal from raleigh' is the wordplay.
'the services of' indicates anagramming the letters (I've seen 'serviced' mean this (to service can mean to repair)).
'from' indicates named letters should be taken away.
'raleigh' with 'gal' taken out is 'reih'.
'reih' anagrammed gives 'HIRE'.
(Other definitions for hire that I've seen before include "Pay to use something" , "Payment for use" , "Employ (for wages)" , "Engage; rent" , "Rent or lease" .)
