Not enough information.
No problem about the spaces between the studs, but how many
windows? If two, there are a lot more holes to cut and fill. And
would you consider doing it yourself?
Go to your local big box, see how big the blower delivery tube is,
get a hole cutter for your drill, cut the holes, save the plugs, get
the blower, blow the insulation in, return the blower and unopened
bags, and rest for the rest of the day.
Next day, take a wet cloth, wipe the inside of the hole, and the
removed drywall circle. Cut the ragged drywall paper around the
circle opening with a sharp cutter, remove rough edges. Drywall
mud to both, put the circle on a pencil, put it back into the hole
with a rotating motion, a bit deeper than the existing drywall. Let
the drywall mud dry, the insulation will keep you from putting the
plug in too deep.
After it's dry, graze over with a tool wider than the hole, pushing
in to fill the openings, including the center 1/4" hole. Let that dry.
Then graze over it again, let that dry as it fills in the bit of
contraction. After all dry for a couple days, with no cracking from
putting too much on too quickly, go over them with a wet cloth to
make it even with the wall, then paint the room.
Or you could have someone else do it, but it's very labor-intensive.
I did a couple of rooms a few months ago, total cost was less than
a hundred dollars.
Care to guess why that room is colder? Got a roof right above,
couple of windows on a corner, with primary weather coming from
that direction?
Have you "tuned" your furnace pipes, or is there a room very near
the air return duct, with wide open vent to that room? Short-circuits
the delivery, the rooms at the furthest distances suffer. Better to
have them be the wide-open, the ones closer to get less because
they get it first.
So you might want to speculate about other reasons for it being
coldest. And is it verified by thermometer or level of complaint?
Betcha if you were to relocate the thermostat to outside his door,
you'd quickly discover the value of tuning the vent pipes.

Too bad the walls described are plaster. A circle cutter for plaster may be hard
to find.

Lenox has sets of carbide hole saws touted for plumbers. If you just
need the largest one, 2 1/2", it may be in stock or can be ordered by
any plumbing distributor. Many electrical distributors also carry
Lenox products. Amazon also has the Milwaukee 49-56-2623 carbide blade
for $15 or so. I've been told these will handle metal mesh lath and
plaster, something I hope I never have to deal with.

Is the ceiling over this room insulated? If not, that's the first thing to
insulate.

Is it stud construction and brick veneer or double brick?
