Not a DIY job unless you have some metal working experience. Call a
musical instrument shop and ank who they use. Alternatively, a shop
that does custom body work or restoration or builds custom motorcycles.
If the instrument is of some value, a pro can make it look like new with
the right tools. Even a hack can make it without the big bend, but it
will be visible.
Toss it in the garbage and buy an identical one at a music store.
If you cant find a replacement, just wrap it with duct tape and tell the
parents a drunken redneck in a rolled over pickup truck, stole it, and
you had to beat the guy over the head with it to get it back.
Take or send the trumpet to a professional trumpet-repair place and only to
a professional trumpet-repair place. Check with the band department at
your local high-school to find out where they take or send their mangled
trumpets. A way to work within your two-day time frame might be to flop
down a couple of hundred bucks for a replacement instrument. Maybe you'll
be able to fool the kid's mother. Best of luck to you and to your
I googled for "trumpet bell repair" and got lots of hits.
If it's not an expensive one, just chuck it and get another. You can
even buy new one for ~100.00, made in China or India. But then El Cheapo
instrument can hinder learning process. They are very stuffy and
tonal quality is minimal.
Fill it with gun powder, add a long fuse. Place it outdoors far from
any buildings, light the fuse, and run like hell. When it blows, the
dent will be gone. Of course the whole trumpet may be gone too, but
that's the risk you take.

Just an opinion, but that wasn't just dropped - it either fell from a
great height or was thrown with some vigor.
She still has to be told - it'll go easier on both you and the kid if
he just fesses up to it now, versus if she finds out after the fact.
If this trumpet is School Property, they have to be told too -
because when the repair shop sees the School Property tag they are
going to get a call anyway.
And unless you're sending it back to the OEM Factory for repairs, they
probably have their own repair connections. Los Angeles Unified runs
their own complete instrument repair shops.
Problem is they need to anneal the metal with a torch flame or a stint
in a heat-treat oven to soften it up first, and that means the whole
thing needs to be stripped of the old lacquer, buffed out, and clear
coated again when it's all done. You can't just hammer it back in
shape, the metal will stretch and distort.
The best way would be to unsolder the bell, anneal it, stick it back
on the spinning lathe on the original form, and gently spin it back
into shape - possibly with a torch shrinking or two, where they heat
it up then hit it with a wet cloth to suck in the stretch. That's
going to be either the original trumpet maker's factory or someone who
has an exact duplicate of the bell form.
Then they solder it back onto the rest of the trumpet, and do the
usual strip buff and lacquer on the whole instrument.
Then again, if this is a $99 (No Name) Indonesia Special you toss it
out - or give it to the instrument repair guys for spare parts.
Then help the kid into a good Conn or Selmer. They sound a whole lot
better, and are far more easily repairable when stuff like this
happens again. And it will.

Bad news is that this needs to go to a repair shop. It'll probably take a
refinishing after the dents are removed. They may be able to use the set o
f magnets I saw for doing this sort of thing, has graduated sizes of RE bal
l magnets and one padded and curved magnet for moving them around. They co
