Does anyone know of a simple, but free PCB layout software.

Or a way to convert .pcb files from EXPRESSPCB to industry standard
format.

I currently use ExpressPCBs layout s/w which is fine for my
applications and great for prototypes. But I want the option to use
other vendors when the volume gets high, i.e. selling kits.


Try gEDA -- free. Full suite of design software. Contain gschem to do
the schematic, then export to pcb [also in the package]. You can print
the layout 1:1 on a transparancy and make your own boards if you want.
