Is there a bathroom in the general vicinity and attic access?
If so you can go into the attic and make sure you have room/access to add a vent where you want. Measure out everything and buy supplies, then cut a hole where you want the new exhaust vent, run ducting up into your existing exhaust line, and hook up a fan. There are some obvious details to overcome like wiring the fan, getting the ducting installed correctly and making the job look clean from inside the room, but it's not overly complicated.
