Opportunity to get money for part of the church (7)
I believe the answer is:
chancel
'part of the church' is the definition.
('chancel' is part of 'church')
'opportunity to get money' is the wordplay.
'opportunity' becomes 'chance' ('chance' can be a synonym of 'opportunity').
'to get' says to put letters next to each other.
'money' becomes 'l' (L can mean 'pounds').
'chance'+'l'='CHANCEL'
'for' acts as a link.
(Other definitions for chancel that I've seen before include "Part of church near altar" , "space for choir" , "where sanctuary may be found" , "Part of church containing altar" , "Where to see choir" .)
