Preacher is ready, real excited (3,6)
I believe the answer is:
lay reader
'preacher' is the definition.
(I've seen this before)
'ready real excited' is the wordplay.
'excited' indicates anagramming the letters.
'ready'+'real'='readyreal'
'readyreal' is an anagram of 'LAY READER'.
'is' is the link.
(Other definitions for lay reader that I've seen before include "who carries out some services" , "One not ordained but licensed to preach" , "Parish assistant" , "licensee in church" , "Minister's assistant" .)
