As far as I know there is no notice board at the airport nor is there an airport newspaper as such.
The local newspaper is: 'The Eastern Daily Press'.
I would guess that either you or your company will have to get in touch with NWI airport security to arrange an airside pass. Perhaps they may help or, at the least, would pass on a note to the Senior Captain at KLM/UK, Eastern and Flybe for posting in their respective crew rooms - if they still have them.
There are a couple of flying schools on the field. They might post a note for you. Indeed, if you get the right girl at the information desk at NWI you might score there too and there used to be some very helpful chaps who worked in Flight Briefing who might put the word out for you. That's airside nowadays. There is also a small airfield nearby at Felthorpe, someone there may be able to help.

I should avoid living to the south of the city, even though you may report and end at uncivilized hours.
Hope this is of some use to you. Norwich is a fine city and the Park and Ride is right beside the airfield.
Good luck.
