hmmm, i guess it depends on who you go to for the set up, I do mine myself but the place i bought the guitar at told me they would do anything free on the guitar i purchased from them. Check around, it really shoudnt be that much
For a buzzing sound try lowering your pickups first before you take it to someone, or rasing your strings etc, unless you really dont like how you tend to the guitar. A drop can push stuff out of place and whatnot. If you take it to a shop, also really shouldnt be that much.
