I get contract as a model (5)
I believe the answer is:
ideal
'a model' is the definition.
(ideal can mean model or perfect)
'i get contract' is the wordplay.
'get' means one lot of letters go next to another.
'contract' becomes 'deal' (I've seen this before).
'i'+'deal'='IDEAL'
'as' acts as a link.
(Other definitions for ideal that I've seen before include "Perfect; a standard of perfection" , "highly desirable" , "without flaws" , "unlikely to be bettered?" , "'Perfect, model (5)'" .)
