You could always use dry film rather than pre-sensitised, sellers can 
supply a length cut from roll, the rolls are 30cm wide which would be 
the limit for your long-edge of the board.  Use a laminator to apply 
it.  Laminate a few boards in a run, and store in a dark place until you 
need them.  Developer is just Sodium Carbonate, a couple of bucks for a 
kg at your supermarket would last a long time (mix 20g to 1 liter for 
developing).
