I've had digital C prints (standard color photographs) made up to 18" at a
cost of approx. $60 at a professional photo lab (Duggall) in New York City.
 (For these the files had to be a minimum of 25 MB for decent resolution.)
There are a whole clump of photo labs that handle this stuff right off
Fifth Ave. around 18th or 19th St.
They also show lots of other options for prints at varying sizes, costs and
qualities.  There are even industrial prints that can make acrylic paint
inkjet prints billboard size (I saw this done back in 1987), but I don't
know the cost.
