Calling all Centre's - Rally Plaques

My local centre are having problems finding a new rally plaque supplier. I wonder if any centres out there could pass me some details of who they use, so my local centre can make contact with them in order to supply them with rally plaques.

I am also aware that some centres have purchased equipment in order to make their own plaques using a computer and laser printer. Any information would be very helpful, and may also proves the way forward in the long term.

Happy Rallying.
