Someone promising better service and reception when you sign new contract (7,7)

'someone promising better service' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'reception when you sign new contract' is the wordplay.
I cannot really understand how this works, but
'reception' could be 'wedding' (wedding reception is a kind of reception) and 'wedding' is located in the answer.
'new' could be 'n' (common abbreviation eg NT for New Testament) and 'n' is present in the answer.
The remaining letters 'planer' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).

'and' is the link.

Can you help me to learn more?
