larger digital printer

Hello All,

I was at the printers (reprographics) yesterday trying to get them to
print a package template (a package that will be cut out and assembled
into a package for MOCK-UP purposes) on 15pt card stock.

The template is 13" by 29"

Unfortunately they said their printer was too small and could not
handle the paper thickness.

I am trying to find a digital printing equipment (because of SMALL
PRINT QUANTITIES) that would be capable of printing this size on 15pt.
card stock.

Do you know where I can find the equipment (and then find the printer
with that equipment).

Thanks.
