I'm sure they won't mind making just a few masked rom parts, but they will
have to charge you for the whole wafer.  Remember, chips are cut out of
wafers, which are pretty big these days (6" or 8"), and yield 1000 or more
chips.  It costs thousands of dollars and takes over a month for a wafer to
pass through all the 30+ processing steps before being shipped to Thailand
for packaging.  That's why there is a minimum order and and time for masked
parts.
