Rachel,
At the risk of asking something you may already have considered -- have you investigated moving production to a board house? For prototypes and small quantities, doing it in house can save some money; for larger scale, I'm guessing there will be a point where the board houses can actually do it cheaper.
Again, apologies if I am pointing in a direction you already investigated or just don't want to go.

My question is, does any one know where to buy pre-sensitized clad, developers, and etching solutions on a large scale? Mouser, Digikey, Jameco, Datak and the like are expensive and the clad is too small to panelize. Google is so frustrating for this, I usually only find Ali Babas market or production houses that charge 50 bucks for a 50 cent board. For the curious, I'm making security products for industrial use.
