Acquire professional remedy (7)
I believe the answer is:
procure
'acquire' is the definition.
(procuring is a kind of acquiring)
'professional remedy' is the wordplay.
'professional' becomes 'pro' ('pro' can be a synonym of 'professional').
'remedy' becomes 'cure' ('cure' can be a synonym of 'remedy').
'pro'+'cure'='PROCURE'
(Other definitions for procure that I've seen before include "Get by special effort" , "Obtain; solicit" , "Acquire" .)
