If the horn is yours, then you should hop in the car, take 595 to University Dr and head north to Tamarac. When you see All County Music on the right, stop! Show them the horn and ask what it would cost to get the dents out.
You also aren't specifit what type of dent work you want done. Do you just want someone to smooth out the dents with a dent eraser or do you want someone to take the time with a rod, ball, and burnishers to get the metal as smooth a possible.
Remember, you are not in a location where there are a ton of music stores that would do dent work on a tuba. (That kind of stuff really hurts the back) What Joe S. might charge could be WAY different than what All County might charge.
My $.02 if the horn is the schools, live with the dents.....they won't hurt anything and no one will see them since you sit in the back!
