1997 Mitsubishi 3000 GT clutch has gone out

1997 Mitsubishi 3000 GT mileage: 133,000. My car is a five speed standard and I believe that the clutch has gone out. The car will go into gear, but when the clutch pedal is let out  the car will not move. I also smell a burning smell such as a clutch going out. What is your recommendation and if it is the clutch is this a job that only a dealer should do? If so, do you have an idea as to what the total cost would be, parts, labor, etc. I'm trying to get an idea since my parents are making me save up for the total repair.
